表面光接枝技术及应用

表面光接枝主要是经光化学反应引发有机材料产生表面自由基从面引发单聚合生成表面接枝链，实施方法有气相法，液相法和连续液相法，表面光接应用领域广泛，可用于聚俣材料的表面改性以及表面功能化。

Surface Photografting Technology and Its Application

Surface photografting polymerization (SPGP) may be intiated by the photoredution reation of an aromatic ketone with a surface H-donors, the chain transfer of a free radical to the surface of organic materials, as well as the fragmentation of a special photo-sensitive group on the surface of materials SPGP may be conducted by a vapor phase process or a liquid phase pocess. The previous applications of SPGP are surface modification of organic materials, especially polyolefins. In recent years, extensive researches have been reported for the functionalization of a polymer surface.
