FIELD: technological processes.
SUBSTANCE: method of obtaining composite membrane materials for the separation of hydrogen from gas mixtures based on hydride-forming intermetallic compounds and polymeric binders is described, comprising mechanical activation treatment of hydride-forming intermetallic compound powder in ball mill, subsequent momentary joint mechanical activation hydride-forming intermetallic compound powder processing with addition of barrier polymer material with a 1-5 min duration, press of metal-polymer composite powders, and subsequent rolling of metal-polymer compact.
EFFECT: membrane with high selective hydrogen permeability, productivity and reliability is obtained.
