表面光接枝技术及应用

Surface Photografting Technology and Its Application

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，从而引发单体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。表面光接技应用领域广泛，可用于聚合材料的表面改性以及表面功能化。

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.
