FIELD: chemistry.
SUBSTANCE: proposed is material containing three adhesive-bonded interpenetrating layers, the first of which is a substrate made from inorganic non-brittle porous material with pore size of 1-30 mcm and thickness of 100-2000 mcm. The second layer is made from spherical particles with size of 0.05-0.5 mcm from oxide or nitride ceramic and has thickness of 1-100 mcm. The third layer is made from zeolite, zeolite-like or mesoporous molecular sieve with pore size of 0.3-15 nm and has thickness of 20-100 mcm. Interpenetration of the said layers into each other is 10-70% of the thickness of the previous layer.
EFFECT: improved membrane operational characteristics.
