We investigated fluororubber metallization using atmospheric UV, which has no environmental impact caused by chemical substances. No marked change was found in the contact angle, which is one indicator of successful plating pretreatment. When FT-IR and XPS were used to assess modification, no change was observed in FT-IR measurements. Modifications were observed in XPS measurements, presumably because modification occurred on the surface layer. When plated on fluororubber that had not been UV-treated, the adhesion strength was approximately 0.5 kN/m. However, results indicated that UV treatment increased it to 1.0 kN / m or more depending on the conditions. Results show that the surface of fluororubber containing calcium carbonate filler becomes smooth and reduces the adhesion strength in conditions of strong UV irradiation intensity.
