Abstract:
1. A method of making a charge dissipative and RF transparent surface of a dielectric polymeric material, said method comprising the step of controllably carbonizing the surface of the polymeric material in a vacuum environment through bombardment of the surface with a beam of rare gas ions having an energy between 2.5 keV and 30 keV, and a total ion fluence level in the range from 1×10 16 ion/cm 2 to 5×10 17 ion/cm 2 , while heating up and maintaining the surface to a temperature varying between 65° C. and 95° C. during the bombardment, in order to achieve: a treated carbonized surface layer with a surface resistivity selectable in the charge dissipative range between 1×10 said treated carbonized surface layer being RE transparent.
