| Abstract: | he ethylene-vinyl alcohol copolymer membrane with polyionically complexationalized layer has been prepared by in situ polyionic complexation from cationically modified surface of EVAL membrane and phosphorylated EVAL aqueous solution, which can be considered as a feasible route to modify the surface of membrane for improving the properties , and which is a way to avoid the using of shielding solvent for the processing of polygonic complexes. The condition for the phosphorylation of EVAL has been studied. The effect of the chemical composition of the polygonic complex membrane on the contact angle, water content, mechanical and thermal properties , as well as blood compatibility have been investigated . |
