<p><P>PROBLEM TO BE SOLVED: To provide a porous film containing inorganic fine particles, the film capable of developing new or high functionality by a composite production process with other materials for incorporating inorganic particles into an organic porous film. <P>SOLUTION: The porous film includes a great number of micropores present therein; and the porous film comprises a composition containing a polymer and inorganic particles. The micropores in the porous film have an average pore diameter of 0.01 to 10μm and a porosity of 30 to 85%. The polymer is preferably at least one kind selected from the group consisting of a polyimide resin, polyamideimide resin, polyether imide resin, polyether sulfone resin, cellulose resin, polyamide resin and polysulfone resin. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
