Synthesis of Poly (vinyl acetate) Based Amphiphilic Surfactant by RAFT/ATRP Polymerization and Preparation Macroporous Materials by Emulsion-templating Polymerization

摘要

Supercritical carbon dioxide (scCO2) is an attractive alternative to conventional solvents[1].However,scCO2 is so feeble that most of polymers and polar masses are difficult to dissolve in it,which limits its applications.This problem can be overcame by preparing emulsion or microemulsion by using amphiphilic surfanctants.Although fluoro-or silicone-based surfactants show good performance in scCO2,the high cost is prohibitive on an industrial scale application.
