摘要：

<正> Enhancement of the surface hydrophilicity of biodegradable poly （D,L-lactic acid）(PLA) films is studied. The PLA films were treated by nitrogen plasma （PLA-N2） and nitrogen/hydrogen plasma （PLA-N2/H2）, respectively. The surface properties and microstructure ofPLA-N2 and PLA-N2/H2 were studied by static contact angle measurement, surface free energycalculation, X-ray photoelectron spectroscopy （XPS） and atomic force microscopy （AFM）. It isconfirmed that the surface hydrophilicity of PLA-N2 and PLA-N2/H2 was higher than that of pristinePLA, and the surface hydrophilicity of PLA-N2 films was better than that of PLA-N2/H2.
