Nanocomposite materials are of great interest because of their superior properties. Besides the traditional synthesis methods that require high temperatures or toxic solvents, photopolymerization technology provides a simple, low-cost, and environmentally friendly route in preparing nanocomposites. In this research, the preparation of blue-light-sensitive triazine derivative-coated silica nanoparticles is presented. The resulting triazine-coated silica nanoparticles can play a dual role, i.e., acting as both photoinitiators to trigger photopolymerization reactions under the irradiation of LED@410 nm and fillers to endow the produced photopolymer nanocomposite materials with enhanced properties. Specifically, the triazine-coated silica nanoparticles can successfully induce free radical polymerization of trimethylolpropane triacrylate efficiently under the irradiation of LED@410 nm and demonstrate comparable photoinitiation ability to the triazine derivative-based photoinitiator. The effects of different loading amounts of triazine-coated silica nanoparticles toward the photopolymerization kinetics are also evaluated. By coating with the triazine derivative, the nanoparticles show good dispersion in the polymer matrix and significantly reduce the shrinkage of the samples during the photopolymerization. Moreover, the photocured nanocomposites exhibit enhanced migration stability and mechanical properties when an optimal amount of triazine-coated silica nanoparticles is added in the formulation.

可见光敏感的三嗪包覆二氧化硅纳米颗粒：具有增强性能的聚合物纳米复合材料的双重作用方法
纳米复合材料因其优异的性能而备受关注。除了需要高温或有毒溶剂的传统合成方法外，光聚合技术为制备纳米复合材料提供了一条简单、低成本、环保的途径。本研究介绍了蓝光敏感三嗪衍生物包覆二氧化硅纳米粒子的制备。所得的三嗪包覆二氧化硅纳米粒子可以起到双重作用，即作为光引发剂在 LED@410 nm 的照射下引发光聚合反应，同时作为填料使所制备的光聚合物纳米复合材料具有增强的性能。具体来说，三嗪包覆的二氧化硅纳米粒子可以在 LED@410 nm 的照射下成功地诱导三羟甲基丙烷三丙烯酸酯的自由基聚合，并表现出与基于三嗪衍生物的光引发剂相当的光引发能力。还评估了不同负载量的三嗪包覆二氧化硅纳米粒子对光聚合动力学的影响。通过涂覆三嗪衍生物，纳米颗粒在聚合物基质中表现出良好的分散性，并显着降低了光聚合过程中样品的收缩。此外，当在配方中添加最佳量的三嗪包覆二氧化硅纳米粒子时，光固化纳米复合材料表现出增强的迁移稳定性和机械性能。
