Microporous membrane of polyethylene-based composite material and preparation method thereof
A microporous membrane of a polyethylene-based composite material, including high density and high crystallinity of polyethylene as a base material. The polyethylene is modified by a modifying agent accounting for 10-25 wt. % of the membrane and including a moderate molecular weight of rubber selected from polyisobutylene (PIB), ethylene-propylene methylene copolymer (EPM), or a mixture thereof, the rubber having a dynamic viscosity of between 50 and 2000 Pa·S at 100° C. and a weight average molecular weight of between 90,000 and 250,000. The modified polyethylene is dissolved in a solvent and a pore-forming agent for pore formation.
