Abstract

A monolayer membrane containing gelling polymer particles having at least one of a basic functional group and an acidic functional group, and having a thickness of less than 5 μm. A composite having a porous carrier and gelling polymer particles having at least any one of a basic functional group and an acidic functional group and filling up the surface pores of the porous carrier. The invention can provide a novel material capable of efficiently separating an acid gas from a mixed gas.
