ABSTRACT:
In a process that can readily modify a surface of a fluororesin product in a short time, the surface of the fluororesin product is irradiated with synchrotron radiation having a wavelength of not more than 100 nm. The synchrotron radiation preferably has a peak of radiant intensity in the wavelength region of about 3 nm to about 6 nm. Such irradiation with the synchrotron radiation is carried out under an atmosphere containing oxygen, a mixture of nitrogen and hydrogen, a mixture of oxygen and hydrogen, or a mixture of oxygen, nitrogen and hydrogen, whereby hydrophilic groups can be introduced into the surface. The fluororesin product of which the surface is modified is improved in wettability with respect to a paint, and adhesiveness to another material.
