摘　　要：将含有探针组分的光敏树脂分别在水中、空气中进行紫外光固化,并对固化材料的表面性能进行了研究.固化膜的表面能测定表明,水中固化的材料表面能大于在空气中固化的材料.X射线光电子能谱(X-ray photoelectron spec-troscopy,XPS)分析表明,探针组分在不同固化介质中的运动方式不同;固化过程中组分的不同迁移、基团翻转最终导致了固化膜表面性能的差别.Photosensitive resin containing special probe reagent was UV cured in water, and surface energy of the cured film was measured. It was found that the surface energy of the film cured in water is higher than that of cured in air. The results of XPS revealed that the movement of probe reagent is different when cured in different mediums, and the difference of surface properties is resulted from the molecular migration and conformational change of the component.
