Abstract
Two series of solid solvent-free polymer membranes comprising poly (ethylene oxide) and poly (acrylic acid) were prepared by using casting technique, and their ion conductivity was examined at ambient temperature and in the present of LiPF6. It was established that the best conductivity, which is in the range 4.2·10-5 - 9.8·10-5 S·cm-1, corresponds to the films obtained on the base of triblock copolymer PAA-b-PEO-b-PAA. The membranes obtained from diblock copolymer PAA-b-PEO have a conductivity two orders of magnitude lower, however, the introduction of 3-9 weight % of LiPF6 made it possible to increase conductivity to 4.49·10-6-1.98·10-5 S·cm-1. Thus, obtained results allow to consider PAA-b-PEO-b-PAA and PAA-b-PEO as a possible solid polymer matrix for proton exchange membranes.
