PURPOSE:To provide a thin water-and-oil repellent film having excellent durability by forming a chemically adsorbed fluorine-containing single molecular membrane on the surface of a surface-roughened film via siloxane bonds. CONSTITUTION:A film 1 of a polyester, trifluorochloroethylene polymer, etc., is subjected to a surface-roughening treatment, brought into contact with a non-aqueous solvent containing a substance having a fluorocarbon group and a chlorosilane group and subsequently washed with a non-aqueous solvent to form a single molecular membrane 2 having an excellent water-and-oil repellence on the film. Since the chemically adsorbed fluorine-containing single molecular membrane 2 is chemically bonded (covalent bonds) to the film substrate via siloxane bonds, the thin water-and-oil repellent film having excellent durability can be formed. |
