摘要:
To provide a process for producing a fluorocarbon film, which is capable of constantly forming a fluorocarbon film excellent in durability and functionality. The process for producing a fluorocarbon film of the present invention is a process for producing a fluorocarbon film at least a part of which is chemically bonded to a substrate surface, and is characterized by conducting, in sequence, step (a) for applying plasma to a substrate surface in a continuous or pulse manner to form active points on the substrate surface and step (b) for applying plasma to the substrate surface in a continuous or pulse manner in the presence of a gas of a fluorocompound represented by the formula CxFy and/or CxFyOz under such a condition that active species impinge on the substrate surface at a relatively lower collision energy than in step (a).
摘要:
A tetrafluoroethylene-ethylene copolymer (ETFE) film, wherein polar groups are present on the surface of the film after a surface treatment, and the surface roughness Ra is at most the surface roughness Ra of the surface of an untreated film; an ETFE film, wherein polar groups are present on the surface of the film after a surface treatment, and the amount of a weak boundary layer is at most one time of the amount of a weak boundary layer on the surface of an untreated film; a laminate employing such a film having an extremely excellent bonding strength; and a process for producing it with a mass production property.
