Preparation and Characterization of Poly( Vinylidene Fluoride) Mem brane Used for Enzym e Im m obilization

Abstract This article w as concerned w ith the poly(vinylidene fluoride)( P V D F)m em brane,w hich w as used to im m obilize enzym e. The m em brane w as prepared by usingphase reverse m ethod. In the research w ork, P E G w as chosen as additive and m anyfactors w ere studied,such as evaporation tim e,coagulation tem perature,cast liquidtem perature,etc. The perm eability and enzym e im m obilization of P V D F m em branew ere evaluated.
