Surface-hydrophilized fluororesin moldings and method of producing same |
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.
