Hydroperoxide groups on polymer surfaces are of interest as initiators for the grafting of polymers such as poly(N-ispropylacrylamide), forming thermoresponsive layers for biomedical applications. In the present study in-situ ATR-FTIR measurements in combination with NO derivatization reactions are performed to investigate the formation of hydroperoxides on polyethylene surfaces after treatment with atmospheric-pressure dielectric-barrier postdischarges. Gas composition and plasma treatment time are varied in order to obtain a maximum density of hydroperoxide groupson the polymer surface.
