(57) [Summary] [Purpose] Suitable for catalysts, catalyst carriers, adsorbent materials that can process specific molecules, deodorizing / deodorizing materials, sustained-release materials, etc. that have pores with uniform pore sizes on the surface. A ceramic porous thin film and a simple and economical method for producing the same. [Structure] The porous ceramic thin film of the present invention can be prepared by simply adding polyethylene glycol or polyethylene oxide to a ceramic sol solution prepared from a metal alkoxide and alcohol amines, coating the substrate, and then heating and baking. The size and distribution density of the pores can be easily controlled by changing the molecular weight and the addition amount of polyethylene glycol or polyethylene oxide produced by the method. |
