Formation of microporous polymeric membranes via thermally induced phase separation： A review

A review of recent research related to micro- porous polymeric membranes formed via thermally induced phase separation （TIPS） and the morphologies of these membranes is presented. A summary of polymers and suitable diluents that can be used to prepare these microporous membranes via TIPS are summarized. The effects of different kinds of polymer materials, diluent types, cooling conditions, extractants and additive agents on the morphology and performance of TIPS membranes are also discussed. Finally new developments in TIPS technology are summarized.
