【Abstract】 The influence of solvents,molecular weight and the content of polyethersulfone on the membrane performances was studied. The results show that:Good solvent has the ability of making pore.With the growth of the content and molecular weight of polyethersulfone, its water flux is reducing,and the retention ratio of bovine serum albumin is increasing.更多还原
