Correlation between contact angle and radical concentration on polymer surface generated by cold plasma irradiation
Source abstract
Abstract
Polypropylene(PP) and polytetrafluoroethylene(PTFE) film were treated by low-temperature oxygen plasma for surface modification.The effects of plasma treatment parameters,chemical structure of materials and gas species on water contact angle(WCA) and peroxide concentration were investigated,respectively.Optimum treatment conditions were found as 4 min,400 W and gas flow 100 cm3/min,by which the WCA of PP film decreased from original 99° to 7°.By comparison of the influence of plasma parameters,chemical structure of materials and gas species on WCA and peroxide concentration,the correlation between WCA and peroxide concentration was found,which indicates a correlation between WCA and radical concentration on the film surface generated by plasma treatment.
