【Abstract】 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, a liquid phase process or a bulk phase process. The previous applications of SPGP are surface modification of organic materials, especially polyolefins. The main properties modified by SPGP are adhesiveness, printability, paintability, dyeability, anti fogging properties, gloss, anti static properties, lubrication, anti staining properties, bio compatibility, heat sealability, and so on. In recent years, extensive researches have been reported for the functionalization of a polymer surface, e.g., the preparation of separation membrane, polymer supported catalysts, reagents, ligands for absorption of metal ions, as well as polymer forming method.更多还原
