FIELD: hydrogen energetic, fuel materials.
SUBSTANCE: invention relates to methods for preparing proton-conducting polymeric membranes used in solid-polymeric fuel members. Method involves modification of films made of aliphatic and aromatic polybenzimidazoles and polyamidobenzimidazoles and copolymers based on hydrophilic heterocyclic compound - 1-vinyl-1,2,4-triazole with hydrophobic fluoroalkyl methacrylates, phosphomolybdenic and silicomolybdenic heteropolyacids of 12-th row and treatment of these films with ortho-phosphoric acid. The proton conductivity of polymeric membranes at room temperature achieves the value 10 - 3 x 10-2 S/cm and increases to 10-1 S/cm in increasing temperature up to 130°C.
EFFECT: improved preparing method.
