讨论了水性体系中，经紫外光（ＵＶ）辐射引发在ＰＥＴ膜表面的丙烯酸接枝聚合反应的实验影响因素，考察了光敏剂、单体浓度以及接枝反应温度对接枝率的影响，以及不同接枝率下接枝膜对水接触角的变化。
The influence factors of graft polymerization of acrylic acid on the surface of PET film initiated by ultraviolet (UV) radiation in aqueous system were discussed. The effects of photosensitizer, monomer concentration and grafting reaction temperature on grafting rate were investigated. Changes of water contact angle of grafted membrane under different grafting.
