Book Description :

Nanocomposites with Carbon-based nanofillers (e.g., carbon nanotubes, graphene sheets and nanoribbons etc.) form a class of extremely promising materials for thermal applications. In addition to exceptional material properties, the thermal conductivity of the carbon-based nanofillers can be higher than any other known material, suggesting the possibility to engineer nanocomposites that are both lightweight and durable, and have unique thermal properties. This potential is hindered by thermal boundary resistance (TBR) to heat transfer at the interface between nanoinclusions and the matrix, and by the difficulty to control the dispersion pattern and the orientation of the nanoinclusions. Thermal Behaviour and Applications of Carbon-Based Nanomaterials: Theory, Methods and Applications explores heat transfer in nanocomposites, discusses techniques predicting and modeling the thermal behavior of carbon nanocomposites at different scales, and methods for engineering applications of nanofluidics and heat transfer. The chapters combine theoretical explanation, experimental methods and computational analysis to show how carbon-based nanomaterials are being used to optimise heat transfer. The applications-focused emphasis of this book makes it a valuable resource for materials scientists and engineers who want to learn more about nanoscale heat transfer. Offers an informed overview of how carbon nanomaterials are currently used for nanoscale heat transfer Discusses the major applications of carbon nanomaterials for heat transfer in a variety of industry sectors Details the major computational methods for the analysis of the thermal properties of carbon nanomaterials

Book Description :

This book presents a systemic view of nanophenomena in terms of disordered condensed media with characteristics arising at various hierarchical levels from nanoagents/nanoparticles through multiple technological interfaces to the creation of micro- or mesostructures with essential nanodimensional effects. These properties can be seen in various schemes for the functionalization of nanocarbon systems, namely, CNTs, GNRs, GNFs, carbon-based nanoaerogels, nanofoams, and so on, where nonregularities characterize surface nanointeractions and various nanointerconnects, resulting in both predictable and unpredictable effects. Beginning with nanosensing and finishing with other forms of functionalized nanomaterials, these effects will define the prospective qualities of future consumer nanoproducts and nanodevices. This book covers all aspects of nonregular nanosystems arising from the fundamental properties of disordered nanosized media, from electronic structure, surface nanophysics, and allotropic forms of carbon such as graphene and fullerenes including defect characterization, to spintronics and 3D device principles. Nonregular Nanosystems will be of interest to students and specialists in various fields of nanotechnology and nanoscience, experts on surface nanophysics and nanochemistry, as well as managers dealing with marketing of nanoproducts and consumer behavior research.

Book Description :

The inspiration for this book came from an American Carbon Society Workshop entitled "Carbon Materials for Advanced Technologies" which was hosted by the Oak Ridge National Laboratory in 1994. Chapter 1 contains a review of carbon materials, and emphasizes the structure and chemical bonding in the various forms of carbon, including the four allotropes diamond, graphite, carbynes, and the fullerenes. In addition, amorphous carbon and diamond films, carbon nanoparticles, and engineered carbons are discussed. The most recently discovered allotrope of carbon, i.e., the fullerenes, along with carbon nanotubes, are more fully discussed in Chapter 2, where their structure-property relations are reviewed in the context of advanced technologies for carbon based materials. The synthesis, structure, and properties of the fullerenes and nanotubes, and modification of the structure and properties through doping, are also reviewed. Potential applications of this new family of carbon materials are considered. The manufacture and applications of adsorbent carbon fibers are discussed in Chapter 3. The manufacture, structure and properties of high performance fibers are reviewed in Chapter 4, and the manufacture and properties of vapor grown fibers and their composites are reported in Chapter 5. The properties and applications of novel low density composites developed at Oak Ridge National Laboratory are reported in Chapter 6. Coal is an important source of energy and an abundant source of carbon. The production of engineering carbons and graphite from coal via a solvent extraction route is described in Chapter 7. Applications of activated carbons are discussed in Chapters 8-10, including their use in the automotive arena as evaporative loss emission traps (Chapter 8), and in vehicle natural gas storage tanks (Chapter 9). The application of activated carbons in adsorption heat pumps and refrigerators is discussed in Chapter 10. Chapter 11 reports the use of carbon materials in the fast growing consumer electronics application of lithium-ion batteries. The role of carbon materials in nuclear systems is discussed in Chapters 12 and 13, where fusion device and fission reactor applications, respectively, are reviewed. In Chapter 12 the major technological issues for the utilization of carbon as a plasma facing material are discussed in the context of current and future fusion tokamak devices. The essential design features of graphite moderated reactors, (including gas-, water- and molten salt-cooled systems) are reviewed in Chapter 13, and reactor environmental effects such as radiation damage and radiolytic corrosion are discussed. The fracture behaviour of graphite is discussed in qualitative and quantitative terms in Chapter 14. The applications of Linear Elastic Fracture Mechanics and Elastic-Plastic Fracture Mechanics to graphite are reviewed and a study of the role of small flaws in nuclear graphites is reported.

Book Description :

Composites with polymer matrices and nano-sized exfoliated fillers demonstrate significant enhancement in mechanical and functional properties over those of monolithic polymers at extremely low filler loadings. From the variety of nano-fillers utilised by researchers to develop commercially viable nanocomposites, carbon based nano-fillers are prominently used to render electrical conductivity in addition to mechanical strength. Amongst these, graphene oxide (GO) is electrically insulating contrary to the rest of carbon-based fillers, and hence not much investigated as a nano-filler so far. However, chemical and/or thermal reduction of GO can restore the electrical conductivity. This transitional behaviour makes GO a promising nano-filler for electronic applications. Besides, the thermal stability and mechanical strength of GO are comparable to graphene at temperate conditions. This research work is aimed at preparation of multifunctional polymer-GO nanocomposite thin films. The multi-layered films are constructed as a sandwich of plain polymer facing sheets supporting an electrospun polymer-GO nano-fibre core. The material formulation is divided into two parts, viz., development of a simple and less hazardous process for synthesizing conductive GO nano-fillers, and manufacturing of polymer-GO nano-fibre mats with electrospinning. The characterisation techniques employed to assess the structure and morphology of synthesized GO include X-ray diffractometry, Fourier transform infrared spectroscopy and scanning electron microscopy and the results confirm the effectiveness of the developed GO synthesis process. Additionally, the partial chemical reduction lead to a severe drop in electrical resistivity of GO sheets, and the observed average resistivity values are amongst the lowest reported till date. An orthogonal experimental design as per Taguchi method was devised to analyse the process parameter effects on the average resistivity value of GO sheets. Poly(methyl methacrylate) was selected as the polymer matrix for this work and plymer-GO nano-fibre mats were generated with electrospinning under controlled environmental conditions, to produce well-dispersed nano-fibres with uniform diameter. Vacuum forming was used to manufacture the sandwich films with electrospun cores. Additionally, electrically conducting, monolayer polymer-GO nanocomposite films were prepared through solution casting. The nanocomposite sandwich films demonstrate very high gas barrier with permeation values of nearly zero, measured during oxygen permeation testing. Modelling of gas barrier property is accomplished with analytical and finite element based numerical modelling tools. The observed high gas barrier is attributed to multi-layered structure, fibrous core and presence of impermeable GO fillers in the nano-fibres. Based on the experimental results, these films are found highly suitable for applications in food and beverage packaging and chemical processing plants. Analytical modelling of electromagnetic interference shielding capability of the solution cast polymer-GO films was conducted. The shielding effectiveness values predicted by the models are positive, but significantly lower than the commercial requirements. However, the theoretical cases for nanocomposite films with moderate improvement in electrical conductivity and increased film thickness yield commercially required EMI SE values, thus confirming the potential of these films as EMI shields This thesis thus reports a comprehensive work covering the synthesis of GO nano-fillers, manufacturing of sandwich thin films with electrospun polymer-GO nano-fibre cores and the experimental characterisation of the fillers and nanocomposite specimens.

Book Description :

This chapter discusses the performance behaviour of ceramic nanocomposites under conditions of thermal shock, i.e. when they are subjected to sudden changes in temperature during either heating or cooling or may be in flame propagating zones. For example, during emergency shut-downs of gas turbines, cool air is drawn from the still spinning compressor and driven through the hot sections: the temperature at the turbine outlet decreases by more than 800°C within one second and ceramic nanocomposite materials are an appropriate choice for such application. Furthermore, such a situation may arise about 100 times during the lifetime of a modern gas turbine engine. Similarly, in the nuclear industries, apart from the moderate shocks inflicted during start-up and shut-down of the system, the plasma-facing material can suffer rapid heating due to plasma discharge. Thus, when a body is subjected to a rapid temperature change such that non-linear temperature gradients appear, stresses arise due to the differential expansion of each volume element at a different temperature. The design principles for the fabrication of high-performance thermal shock resistant ceramic nanocomposites with improved mechanical properties are highlighted in this chapter. Moreover, the pertinent factors such as interface characteristics, densification methods, superplasticity and the role of nano-size particulate dispersion, which are responsible for the development of thermal shock resistant and flame retardant nanoceramic materials, are addressed and reviewed. Various test methods for the characterisation and evaluation of ceramic nanocomposites are described. Finally, the new concept of materials design for future structural ceramic nanocomposites is discussed for safe applications in high-temperature thermal shock zones.

Book Description :

This unique book is the first treatment of nanotechnology as the science controlled by the behaviour of thermodynamic small systems. It provides comprehensive discussions on fullerenes as building blocks, Raman spectroscopy as a powerful diagnostic tool, and nanotechnology as the technology bridging the gap between human-made and biological materials systems. Aimed at graduate students, scientists, researchers, and educators interested in academia, government and industry, the text is divided into four chapters. The first covers the potential of nanotechnology to develop a better, deeper understanding of the physical and chemical phenomena observed in natural systems. It also contains a section introducing nanotechnology to the public in simple, non-scientific terms. The second chapter is devoted to Raman spectroscopy and could in itself serve as a basis for a short course on its applications in materials science. The third section covers fullerenes and presents their history and development as well as discussing the structure and production of zero-dimensional, one-dimensional, and two-dimensional fullerenes. The fourth and final chapter serves as a correlation discussion and over view. It emphasizes the unique nano-phenomena exhibited by the fullerene systems as carbon based nanostructured systems. This chapter, and therefore the book, concludes with a discussion on the potential of nano-science and technology to shape the future of human society.
