Abstract In this paper, plasma polymerization of mixed monomer gases was studied. In the films, the elements derived from each monomer are contained, and they are distributed homogeneously at a certain depth. The films are made up by the copolymers in which both monomers are combined. The chemical compositions of the copolymers can be controlled by changing the proportions of the two monomer gases. The films having gradual compositional change toward depth can be prepared by using a mixture of two monomer gases and changing their proportions during the plasma polymerization. These copolymeric and gradient copolymeric films were formed on porous glass hollow fibers, and gas permeability of these composite membranes was measured. The gradient copolymerization methods are available for the preparation of the membranes for gas separation.
