The effects of different factors on the laser-induced graft polymerization on the PET surface were analyzed, and the mechanisms were discussed. The factors were: 1 Monomers with smaller molecules resulted in better modification than polymeric monomers. Acrylamide monomer was chosen as hydrophilic modifier finally; 2 Higher concentration of the monomer solution favored the graft reaction; 3 With the increasing laser fluence, the surface hydrophilicity of PET films increased at first, then decreased. More laser pulses led to a more hydrophilic surface; 4 Benzophenone as a photosensitizer hindered the graft polymerization; 5 The homopolymer retardant of ammonium iron sulfate hexahydrate in a proper concentration retarded the formation of homopolymers and promotes the graft copolymerization; 6 The solvent of monomer solution also affected the graft reaction. Different solvents functioned in different ways. Ethanol can promote the graft reaction because of the activity of hydrogen in its structure; 7 pH value of the monomer solution affects the polymerization rate, and a lower pH value was favorable to the graft reaction.

这些影响因素的作用分别为：1小分子单体的表面改性效果好，确定以丙烯酰胺为亲水性改性单体；2较高的单体溶液浓度有利于接枝反应；3激光能量密度增大，薄膜表面亲水性先显著增强，后又减弱；激光脉冲次数越多，改性后表面亲水性越强；4光敏剂BP对PET表面接枝聚合反应有阻碍作用；5适当浓度的均聚物抑制剂六水合硫酸铁铵能减少单体均聚物的生成，促进接枝聚合；6单体溶液的溶剂也影响接枝聚合的反应进程，不同溶剂的影响作用原理不同，含较活泼氢的乙醇能促进接枝反应；7溶液pH值影响单体聚合速率，pH值较低有利于接枝反应。
