Surface Treatment of Polymers by Simultaneous Exposure to VUV and Nanometer-Sized Particles in Helium Atmospher

A new surface treatment for polymers in helium at atmospheric pressure was demonstrated. By focusing the strong absorption of vacuum ultra-violet light at the wavelength between 60nm and 80nm for polymers and high transparency in helium gas of the vacuum ultra-violet light at the wavelength over 50.4nm, we developed the new process for surface treatment of polymers for making bonds between polymer surfaces and painting over polymer surfaces in helium atmosphere by simultaneous exposure to VUV and nanometer-sized particles.
