The surface modification of a polyethylene (PE) film using an air Coplanar barrier discharge plasma at atmosphere pressure
In this paper,modification of the surface properties of polyethylene (PE) films is studied using air coplanar barrier discharge plasma at atmosphere pressure.The diffuse plasma appears on the surface of the device.The treated samples are examined by water contact angle measurements,fourier transform infrared attenuated total reflection spectroscopy (FTIR-ATR),X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy(SEM).With treatment time increasing,the water contact angle changes from the value of 92°of the untreated PE surface to the minimum value of 51°after treatment time of 50s.The results show some oxidized species are introduced into the samples surface by the plasma treatment and the changeable tendency of the water contact angle with the treatment time is the same as that of the O concentration on the treated sample surface.From the SEM,the surface roughness of PE samples increases with the treatment time increasing.
