Process for preparing hydrophobic material.

摘要

Disclosed herein is a process for preparing hydrophobic material comprises applying a hydrocarbonous polymer compound solution to the surface of material to be treated, vaporizing the solvent of the solution, and then fluorizing the polymer compound to coat the surface of the material to be treated with the fluorized polymer compound. According to the present invention, the hydrophobic material of which almost all the surface is coated with the fluorized coating layer is obtained through a relatively simple operation. The material possesses the excellent ability of gas supply and the durability for a long period of time.
