Book Description :

Abstract: In this work, the rheology of two types of polymeric suspensions, namely waterborne coatings and polymer/nanoclay and polymer carbon nanofibers (CNF) is studied. The steady shear viscosity as a function of shear rate of a metallic automotive basecoat is measured and the data is fitted to several constitutive models. The pressure drop of the paint flow in a straight circular pipe is measured in a pilot plant, and it is compared with the simulations using the constitutive models. It is found that Sisko model works very well for a wide range of flow rates. At the same time, the paint shows abnormal temperature effects on the rheology in the range of 10-45C, where the steady shear viscosity decreases and then increases with temperature. In the study of the rheology of CNF suspensions with a Newtonian fluid as solvent, it is found that the dispersion of the CNFs determines the suspension rheology. Steady shear viscosities of untreated sonicated suspensions are higher than that of better dispersed treated sonicated suspensions, due to the existence of large clumps and strong inter-particle interactions. Morphology investigations show that the acid treatment of the treated CNFs disintegrates the agglomerates exists in the as-received CNFs and therefore improves dispersion. However, the treatment also weakens the CNFs, as the subsequent sonication breaks most of them. Extensive shear and extensional rheological studies have been conducted on the polystyrene/CNF composites made by melt blending (MB) and solvent casting (SC) methods. The results show that the elastic and viscous moduli (G' and G") of the composites are greatly improved with higher CNF concentrations. Higher CNFs in the SC composites have more impact on the increase. Transient behavior, including transient shear viscosities and normal forces, can be related to the evolution of the CNF orientation and structure. Orientation of the CNFs induced by shear flow is measured, both as a function of the shear strain and of the shear rate. Our models show that the rheology of the composites can be captured and the orientation of the CNFs can be predicted and coupled with the rheology.

The book then delves deeper into the technology behind PLA foaming, such as PLA/gas mixture characteristics, solubility, interfacial tension behaviors and crystallization kinetics of various types of PLA and their compounds. The foaming behaviors and mechanisms of various types of PLA and PLA compounds are extensively analyzed and discussed through different manufacturing technologies, namely extrusion foaming, foam injection molding and bead foaming. Interest in Poly(lactic acid) and PLA foams is extremely high – particularly as a potential replacement for styrenic resins – and the price of PLA resin is lower than ever before. This biopolymer has significant potential to improve the sustainability of the plastics industry. Polylactide Foams have a range of potential applications, such as in construction, packaging, insulation, biomedical scaffolds, and others. However, processing and performance of PLA are not at the same level as other non-biodegradable resins.

Book Description :

Polymer nanocomposites have been a keen area of research interest for the past decade. In place of traditional fillers, nanocomposites use significantly smaller amounts of reinforcing material with very high surface area per unit volume. The promise of polymer nanocomposites ranges from improved mechanical strength, reduced thermal expansion, improved barrier properties, decreased flammability, to electrical conductivity, but all of these potential improvements depend on good dispersion of the nanocomposite filler. The goal of this research has been twofold: first, to develop an effective technique in which melt rheology can be used to characterize exfoliation of nanoclay in this important class of materials and to determine the effect that applied stresses have on such polymer nanocomposite systems. To date, the use of melt rheology in characterizing exfoliation in polymer nanocomposites has been limited to qualitative assessment of a solid-like plateau that evolves in the elastic modulus due to the dispersing nanoclay particles forming and acting as a reinforcing network structure typically known as a "house of cards" morphology. By applying scaling laws from fractal gel rheology to linear rheology for polypropylene and polystyrene nanocomposite systems, melt rheology has been used effectively to determine the fractal dimension of the clay network structure in nanocomposites. These scaling laws have also allowed for percolation behavior to be determined for the nanocomposite systems and with it aspect ratios for the particles have been determined. These rheological predictions have shown to prove accurate when compared to direct measurements from X-ray scattering and TEM microscopy analyses. High shear stress mixing regimens have shown to be successful in creating well dispersed polystyrene nanocomposites. For polypropylene nanocomposites, a new blend creation mechanism, multilayer coextrusion has been employed to make thin films of nanocomposite materials. Characterizing the mechanical and thermal properties of these films suggests multilayer coextrusion can be used to create dispersed nanoclay morphologies in polymer melts. This thesis has provided a new and reliable rheological tool for quickly assessing dispersion and has suggested a new multilayer coextrusion technique to make tailored nanomaterials.
