Preparation of UHMWPE microporous membranes via TIPS method and supercritical propane extraction

Abstract

In this thesis, the preparation technology of UHMWPE microporous membranes was researched via TIPS method and supercritical propane extraction when liquid paraffin(LP) was used as diluent. Under the conditions of 100°C, 9MPa, 2h, 1.5kg/h, the extraction efficiency of extracting LP is up to 98.5% and the porosity of membranes is 32.65%.
