Abstract
A composite porous ceramic hollow fiber obtained by dipping a porous ceramic hollow fiber into a carbon precursor-forming solution, picking up and drying the dipped porous ceramic hollow fiber, heating the thus deposited carbon precursor-forming film, thereby obtaining a carbon precursor thin film, and heating the carbon precursor thin film at a carbon precursor thermal decomposition temperature, thereby forming a carbon thin film on the porous ceramic hollow fiber has a permeance about 100 to about 1,000 times as high as that of an organic thin film and a separation coefficient as high as that of the organic thin film.
