Abstract:
1. A process for manufacturing a hydrophobized microporous film, including: forming a microporous film on a substrate by a method consisting of forming a film including an aggregated material of an organic monomer and heating the substrate so that the aggregated material of the organic monomer is thermally decomposed, said heating being performed by a process selected from the group consisting of radiation by infrared lamp, moving the substrate closer to a high-temperature body, elevating a temperature of a Peltier element that is in contact with the substrate, employing microwave heating, spraying a high temperature gas over the substrate, and combinations thereof; immediately after forming said microporous film, supplying a gaseous mixture composed of a silylation gas and an inert gas in an apparatus containing said substrate with said microporous film formed thereon at a temperature of said substrate and said temperature being equal to or higher than a dew point temperature of the silylation gas and equal to or lower than a vaporizing temperature of the silylation gas; stopping the supply of said gaseous mixture into said apparatus and heating said substrate so that said microporous film has achieved a silylation in said apparatus.
