Nano-modification of polyester has become a research hotspot due to the growing demand for high-performance polyester. As a functional carrier, silica nanoparticles show large potential in improving crystalline properties, enhancing strength of polyester, and fabricating fluorescent polyester. Herein, we briefly traced the latest literature on synthesis of silica modifiers and the resultant polyester nanocomposites and presented a review. Firstly, we investigated synthesis approaches of silica nanoparticles for modifying polyester including sol-gel and reverse microemulsion technology, and their surface modification methods such as grafting silane coupling agent or polymer. Then, we summarized processing technics of silica-polyester nanocomposites, like physical blending, sol-gel processes, and in situ polymerization. Finally, we explored the application of silica nanoparticles in improving crystalline, mechanical, and fluorescent properties of composite materials. We hope the work provides a guideline for the readers working in the fields of silica nanoparticles as well as modifying polyester.
由于对高性能聚酯的需求不断增长，聚酯的纳米改性已成为一个研究热点。作为一种功能载体，二氧化硅纳米粒子在改善聚酯的结晶性能、增强聚酯强度以及制备荧光聚酯方面具有巨大潜力。在此，我们简要追溯了关于二氧化硅改性剂合成及所得聚酯纳米复合材料的最新文献并进行了综述。首先，我们研究了用于改性聚酯的二氧化硅纳米粒子的合成方法，包括溶胶 - 凝胶法和反相微乳液技术，以及它们的表面改性方法，如接枝硅烷偶联剂或聚合物。然后，我们总结了二氧化硅 - 聚酯纳米复合材料的加工工艺，如物理共混、溶胶 - 凝胶法和原位聚合。最后，我们探讨了二氧化硅纳米粒子在改善复合材料的结晶、机械和荧光性能方面的应用。我们希望这项工作为从事二氧化硅纳米粒子以及聚酯改性领域的读者提供指导。
