Surface Modification of Polypropylene Melt Blown Non-woven Using Atmospheric Pressure Dielectric Barrier Discharge Plasma

摘要

In this paper, polypropylene (PP) melt blown non-woven fabric is treated by atmospheric pressure N_2 or N_2/CO_2 dielectric barrier discharge (DBD) plasma. The variation of the surface hydrophilicity of PP sample is experimentally investigated by surface water contact angle, Fourier transform infrared reflectance spectroscopy (FTIR-ATR). The results show that the hydrophilicity of PP sample is considerably improved as long as the very short plasma treatment time (several seconds). However, the treatment effect of atmospheric N_2/CO_2 plasma is worse than that of atmospheric N_2 plasma.
