VUV Enhanced XeF2 Fluorination of Polymer Surfaces

Exposure of polyethylene and polystyrene to xenon difluoride (XeF 2 ) in the presence of vacuum ultraviolet (VUV) irradiation emitted from O 2 ,N 2 , Ar, Kr and Xe electrical discharges gives rise to surface fluorination. The extent of reaction is found to be governed by the synergistic effect betwe...

Description
Summary:Exposure of polyethylene and polystyrene to xenon difluoride (XeF 2 ) in the presence of vacuum ultraviolet (VUV) irradiation emitted from O 2 ,N 2 , Ar, Kr and Xe electrical discharges gives rise to surface fluorination. The extent of reaction is found to be governed by the synergistic effect between the VUV absorption characteristics of the XeF 2 feed gas and the polymer substrate. Polystyrene in combination with krypton electrical discharge emission lines yields the most fluorinated surface.
