Abstract
A process for surface treatment of a vulcanized rubber is disclosed, said process comprising: generating a nonequilibrium low-temperature plasma under atmospheric pressure between a cathode and an insulating dielectric which is interposed between the cathode and an anode while introducing a gas for generating plasma to a plasma-generating region between the cathode and the insulating dielectric, placing the vulcanized rubber in air and outside the plasma-generating region so that a surface of the vulcanized rubber faces the plasma-generating region, and directing the gas from the plasma-generating region toward the surface of the vulcanized rubber so that the gas impinges against the rubber surface for effecting surface treatment.
