摘　　要：以甲基丙烯酸酯改性硅油、二脲烷二甲基丙烯酸酯(UDMA)和甲基丙烯酸异冰片酯(IBMA)为主要原料合成了一种有机硅纳米凝胶(Si15M)。以其为添加剂加入到三乙二醇二甲基丙烯酸酯(TEGDMA)紫外光固化体系中,考查了其对固化膜性能的影响。研究表明,随着纳米凝胶添加量的增多,固化膜硬度、断裂伸长率、凝胶率有不同程度的增加,而其玻璃化转变温度、拉伸强度及吸水性有不同程度的下降。A polysiloxane-modified nanogel （Si15M） was synthesized with methacrylate-modified polysiloxane, biurethanedimethacrylate （UDMA） and isobornyl methacrylate （IBMA） as the main raw materials. The nanogel was used as the reactive additive for the triethylene glycol dimethacrylate （TEGDMA） UV-curable systems, and the influence of the nanogel on the properties of UV-cured films was studied. The results showed that with increasing the content of polysiloxane-modified nanogel, the hardness, elongation at break and gel yield of UV-cured films were increased, but their glass-transition temperatures, tensile strength and water absorption were decreased.
