Study on the Preparation and Characteristics of Calcium Carbonate/Polyvinylidene Fluoride（CaCO_3/PVDF）Hybrid Membrane

摘要

In this paper, calcium carbonate/polyvinylidene fluoride hybrid membrane was prepared through blending method. The effects of contents of CaCO_3 and its particle size on structure and property of hybrid membrane were investigated. Experiment results indicated that with increase of CaCO_3 content, both membrane's flux and strength show firstly rising up, and secondly going down. Different sizes of CaCO_3 particles also have effect on performances of membranes. So proper content of CaCO_3 and its particle sizes were helpful to high membrane flux and strength.
