摘要

Abstract

The mechanical behavior of polyionic complex (PIC)membranes derived from polyvinyl alcohol(PVA) or ethylene-vinyl alcohol copolymer (EVA) have been investigated. The presence of ethylene block segment in the backbone of polyions can endow PIC membranes with more toughness. Increasing the degree of substitution of the polyions

the formed PIC becomes harder and more brittle. Under the environment of relative humidity (R. H. ) of 40%

the tensile strength

relative elongation and modulus of PICs are at about 300kg/cm2

10% and 8×103kg/cm2

respectively

whereas inthe environment of 90% R.H.M these of PICs derived from EVA are at about 90 kg/cm2

150% and 13kg/cm2

respectively

better than that of PVA derived polyionic membrane and ordinary PIC such as Ioplex 101. The permeabil-ity of PIC membranes derived from EVA have also been studied.
