Abstract
A surface of a given base material is hydrophilized by irradiating, for example, a vacuum ultraviolet light to itself. Then, on the surface is formed a monomolecular film made of a fluoroalkylsilane preferably having at least one of a long fluoroalkyl-chain and a long alkyl-chain which preferably have lengths of not less than 1 nm. Then, the base material and the monocular film are thermally treated and thereby a member having a high lubricative surface can be obtained which has strong couplings between the base material and the molecular film through a dehydrating condensation reaction.

A method for producing a high lubricative surface comprising the steps of:
- preparing a base material,
- hydrophilizing a surface of the base material, and
- chemically reacting the surface of the base material with molecules of a fluoroalkylsilane that is 1-5 nm long, thereby forming on the surface of the base material a monomolecular film made of the fluoroalkylsilane.
A member having a high lubricative surface comprising a base material and a monomolecular film comprising a fluroalkylsilane that is 1-5 nm long, wherein the member is produced by a process that includes hydrophilizing the base material.
