摘要

A plasma surface treatment of biaxially oriented polypropylene (BOPP) film was carried out with dielectric barrier glow discharge (DBGD) in Ar/air. The paper studied the effects of the ratios of Ar/air plasma on the BOPP surface modification. The results indicated that the efficiency of the plasma surface modification was improved with increasing treatment time and power density with DBGD in Ar/air. The water contact angle increased first and then decreased with the increase of the Ar/air mixture rate. The DBGD gives a better surface modification than filament discharge. The ageing behavior was influenced by the mixture rate of Ar/air, but the water contact angle of the treated sample was always less than that of un-treated sample.
