Challenging multiphase complex fluids for applications

Abstract

Modern processing technology is calling the scientific understanding of dynamic processes, where the science of complex fluids plays a central role. We summarize our recent efforts using the generic approaches of multi-scale physics of complex fluids on apparently irrelevant processes, i.e. the mixing of polymer blends, the processing of thermoplastic(TP) toughened thermosetting(TS) composites using phase separation of TP in TS, as well as the enhanced oil recovery using polymer soft gel. It is emphasized that the thorough physical understanding in multi-scales of time and space through the joint efforts of experiment and theory in each scale is the key issue for the modeling of various processes.
