Abstract

Abstract:

The preparation techniques of immerse precipitation, thermally induced phase separation and thermally assisted evaporative separation for PVDF microporous membrane are reviewed. The research focuses on the effects of solvents, non-solvents, coagulation temperature, additives, evaporation time on the properties and structure of PVDF membranes. The hydrophilic modification of PVDF microporous membrane is introduced briefly.

Key words: polyvinylidene fluoride, microporous membrane, immerse precipitation, thermally induced phase separation , thermally assisted evaporative separation, hydrophilic
