FIELD: polymer materials.
SUBSTANCE: invention relates to composite proton-conducting polymer membranes based on (co)polymer linear matrices, which are copolymers of 1-vinyl-1,2,4-triazole with fluoroalkyl methacrylates, aliphatic and aromatic polybenzimidazoles and polyamidobenzimidazoles. Matrices are structured by hardening in solution with the aid of thermosetting plastics, such as epoxy-containing copolyimide, polyaminoimide resin, pyrimidine-containing oligo-bis-itaconimide, and poly-bis-benzotriazolimide resin, at temperature 100-230°C or UV radiation, and then doped with orthophosphoric acid. Invention also relates to a method for preparing above-defined membranes.
EFFECT: increased proton conductivity and moisture absorption of polymer membranes.
