This research was conducted to analyze the compatibility of used monomers and produce the high functional POSS-based ophthalmic polymer containing silicone monomers and neodymium nanoparticle. Synthesized silicone polymer (SiD), trimethylsilylmethacrylate (TSMA), -vinyl-2-pyrrolidone (NVP) and neodymium nanoparticles were used as additives for the basic combination of polyhedral oligomeric silsesquioxane (POSS), and methyl methacrylate (DMA). And also, the materials were copolymerized with ethylene glycol dimethacrylate (EGDMA) as the cross-linking agent, azobisisobutyronitrile (AIBN) as the initiator. It is judged that the POSS-co-NVP polymer is optically good and thus have good compatibility. Especially copolymerization with TSMA showed high oxygen permeability, but with SID considered to be more stable judging by lens shape. Physical properties shows that the neodymium nanoparticle increases the wettability while maintaining water content. These materials are considered to make synergy effect each other, so it can be used in functional hydrogel ophthalmic lenses.
本研究旨在分析使用的单体的相容性，并制备出含有硅单体和钕纳米粒子的高功能性 POSS 基眼科聚合物。合成的硅聚合物（SiD）、三甲基硅基甲基丙烯酸酯（TSMA）、-乙烯基-2-吡咯烷酮（NVP）和钕纳米粒子被用作多面体低聚倍半硅氧烷（POSS）和甲基丙烯酸甲酯（DMA）基本组合的添加剂。并且，将这些材料与乙二醇二甲基丙烯酸酯（EGDMA）作为交联剂、偶氮二异丁腈（AIBN）作为引发剂共聚。判断 POSS-co-NVP 聚合物具有良好的光学性能，因此具有良好的相容性。特别是与 TSMA 的共聚显示出高的氧气透过率，但考虑到透镜形状，认为 SID 更稳定。物理性能表明，纳米钕粒子在保持含水量的同时增加了润湿性。这些材料被认为具有协同作用，因此可用于功能性水凝胶眼科镜片。
