Anisotropic flat sheet membrane formation via TIPS: thermal effects

摘要

The use of liuqid-liqudi thermally inducd phase separation (TIPS) to produce cellular flat sheet membranes with an anisotropic nature was investigated theoretically and experimentally for the model system isotactic polypropylene (iPP) and diphenyl ether (DPE). Anisotropic structures were obtained experimentally by evaporating diluent from one surface of a polymer-diluent solution prior to pahse separation.
