Abstract
In this study, graphite or zeolite 4A was mixed with poly(acrylonitrile-butadiene-strene) (ABS) to make hybrid films, and permeation characteristics of air and water vapor through these films were investigated. In all cases, gas permeabilities of hybrid films were lower than that of pure ABS films. The permeability decrease of oxygen was slightly larger than that of nitrogen, resulting in the little decrease of $O_2/N_2$ selectivity. In addition, the water vapor transfer rates (WVTR) of hybrid films were about half of ABS film's. The decrease of permeabilities may be owing to the increase of tortuosity for diffusion in hybrid films.
