Abstract

The present invention relates to a process for modifying a polymer surface by irradiating ion particles with energy on a polymer surface, while blowing the reactive gas directly on the polymer surface under vacuum condition, to decrease the wetting angle of the polymer surface. The process for modifying the polymer surface according to the present invention can be widely used in the application fields of polymers because it provides effects of increasing the spreading of aqueous dyestuffs, increasing adhesive strength with other materials and inhibition of light scattering by decreasing the wetting angle of the polymer surface.
