Hydrodynamics of Macromolecular and Nano-Composite Materials

摘要

This report summarizes the research work conducted during the period funded by the AFOSR grant. The PI has conducted a series of research projects on (a). development of hydrodynamic theories for inhomogeneous nematic liquid crystal polymers, cholesteric liquid crystals, blends of liquid crystal polymers and flexible polymer solutions or melts, biaxial liquid crystal polymers or suspension flows of biaxial nano-particles; (b). studies of nematodynamics as well as morphology of inhomogeneous nematic liquid crystal flows as well as relevant temporal chaotic and spatial chaotic behavior in the fascinating high performance material; (c). development of an effective theory to characterize the effective material properties for the nano-suspension and/or liquid crystal polymer; (d). studies of coupled flow and magnetic and electric field assisted processing for liquid crystal polymers as well as suspension flows. These subprojects have revealed a great deal of the flow- orientation couple dynamic in the flowing materials leading to some potential applications in the military and industries.
