Kind Code:

A1

Abstract:

The problem of an aspect of the present invention is to provide a new organic-inorganic hybrid membrane composite having good permeance, and techniques related thereto. The organic-inorganic hybrid membrane composite according to an aspect of the present invention comprises a porous support layer and an organic-inorganic hybrid membrane formed on the porous support layer, and has an air permeation amount of 10000 L/(m2･h). The organic-inorganic hybrid membrane includes a matrix resin and an inorganic filler having gas selectivity. The content of the inorganic filler having gas selectivity in the organic-inorganic hybrid membrane is greater than or equal to 35 mass%. The inorganic filler having gas selectivity includes zeolite. The framework density in the case that the T element of the zeolite is all silicon is less than or equal to 16.0 T/1000 Å3. The membrane thickness of the organic-inorganic hybrid membrane is 0.05 to 50 μm inclusive.
