<p>PURPOSE:Fine particles of zeolite, layer-utilized compound or crystal lattice- utilized compound are filled in the micropores of a porous support, so that a thin film is formed only in the micropores to obtain a composite membrane having host/guest intercalation, molecular sieve and catalytic effects. CONSTITUTION:Filtrate obtained through the ultrafiltration of an aqueous solution of fine particles of layer-utilized or crystal latticeutilized compound such as zeolite or monmorillonite is compressed into a porous support. Then the fine particles are fitted into the micropores of a porous support by suction and ultrasonic treatment. A composite membrane thus obtained is available for separation, transport, sensor, analysis, etc. as a composite substance having host/guest intercalation effect, and also is used as a composite membrane aimed at molecular sieve effect or catalytic effect.</p> |
