Plating Technology for Fluorocarbon Polymer Films Using Atmospheric-pressure Nonthermal Plasma Graft Polymerization

A low-environmental load surface modification technique for plating the fluorocarbon polymers films is developed using an atmospheric-pressure argon and acrylic acid vapor nonthermal plasma graft polymerization. The results of the T-type peeling test show that the peeling strength of copper plating on the treated PTFE (polytetrafluoroethylene) film is approximately 46 times greater than that on the untreated film. With scanning electron microscope analysis of the surface of the copper plating on the treated PTFE, it is confirmed that the hydrophilic surface of the treated film contributes to uniform copper plating.
