Bio/Research
Our research focuses on the integration of continuum analysis with molecular details in polymeric materials processing. Areas of current interests include the microstructural rheology and processing of complex fluids, the formation of nanostructures in nanofibers, and the occurrence of viscoelastic instabilities in polymer flows. In particular, we have recently laid the new foundation for experimental and theoretical studies on advanced, scalable manufacturing processes based on the flow instability such as gas-assisted electrospinning and Taylor-Couette (T-C) reactors with axial flow. Incorporation of high loading of inorganic precursors into water-soluble polymers in gas-assisted electrospinning gave rise to cost-effective, facile production of metallic and ceramic nanofibers. Comprehensive mesoscale modeling and simulation studies on the dynamics of confined assembly of block copolymer/nanoscale filler systems lead to ceramic and metallic nanofibers with tailored nanostructures such as ordered mesopores which are being used in reaction studies in various catalysts and energy storage devices. The newly developed model reactor based on continuous T-C offers fundamental studies on the effect of flow structures on crystallization, absorption, extraction and chemical reactions.
