Surface Wettability of Polypropylene Non-Woven Using Atmospheric Pressure N2 Dielectric Barrier Discharge Plasma
In this thesis, the atmospheric pressure nitrogen dielectric barrier discharge (DBD) plasma modified polyproylene (PP) melt blown non-woven surface wettability are investigated. The change of surfaces physical and chemical properties are studied by water contact angle measurement and X-ray photoelectron spectroscopy (XPS) before and after plasma treatment. The experimental results indicate the surface hydrophilic can be greatly improved when the PP simples is treated by atmospheric pressure nitrogen DBD plasma for a short time. And a large number of oxygen-containing and nitrogen-containing functional groups are inplanted on the PP non-woven sample surface.
