Abstract
A process for modifying the surfaces of a polymer, ceramic, ITO or glass by irradiating energized ion particles onto the surfaces of the polymer, ceramic, ITO or glass, while blowing a reactive gas directly over the surface of the polymer, ceramic, ITO or glass under a vacuum condition, to decrease the wetting angle of the surface. The process can be widely used in the 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 material surface.
Claims9
A process for modifying the surface of a polymer, comprising:
- irradiating ion beam particles onto the surface of the polymer while directing a reactive gas onto the polymer surface under a vacuum condition.
A polymer material, wherein a wetting angle of the polymer surface is decreased or an adhesive strength thereof is increased, by irradiating ion beam particles onto the polymer surface while directing a reactive gas onto the polymer surface under a vacuum condition.
