摘要： The invention provides surface-modified hydrophilic fluororesin moldings. The surface of a fluororesin molding is at least partly hydrophilized by irradiating at least part of the fluororesin molding with ultraviolet laser light not longer than 400 nm in wavelength in a state such that the molding is in contact with gas-treated water prepared by introducing into water a gas such as hydrogen gas, nitrogen gas or a rare gas or with some other specific aqueous liquid. The thus-obtained fluororesin moldings are suited for use, for example, as materials of artificial blood vessels excellent in antithrombotic property, and contact lenses free of modification-due discoloration. Further, they are expected to find a wider range of application where their performance characteristics are to be utilized.

摘要： The present invention relates to a process for hydrophilizing a porous material made of a fluorine resin comprising irradiating an ultraviolet laser beam on the porous material impregnated with an aqueous solution of hydrogen peroxide or water-soluble organic solvent. According to the process, the chemically and physically inactive surfaces including the inside of the micropores of the porous materials made of fluorine resins can be sufficiently hydrophilized without deteriorating the excellent heat resistance, chemical resistance and the like of the fluorine resins.
