Abstract
The preparation of grafted copolymers for electrochemical devices by chemical grafting copolymerization of acrylic acid and α-, β-, β-trifluorostyrene to a film fluorinated copolymer of hexafluoropropylene with vinylidene fluoride is described. The grafted copolymers contained carboxyl groups and the sulfonation process was carried out for additional introduction of ionic sulfo- groups. The optimal conditions for the process have been determined, which make possible to obtain grafted copolymers with a wide range of electrochemical and physical-mechanical properties. The resulting products in the form of ion-conducting membranes can be used as part of current sources and other electrochemical devices and have a specific volumetric electrical resistance of 0.46—1.41 Ohm.m, exchange capacity 1.45—1.62 meq / g, moisture content 25—62%, breaking stress 0.82—1.08 MPa.
