摘要
纳米GeO2是用于光学性能优异、耐老化性能好的高品质聚酯生产的主要催化材料,目前该催化材料的制备研究在国内鲜有报道,国内聚酯企业大都通过从国外进口纳米GeO2材料以满足生产需求,这较大地限制了国内高端聚酯产业的发展。本文讨论了聚酯合成的催化机理及发展现状,介绍了纳米GeO2用于聚酯催化的优势,分析了已有纳米GeO2材料的制备方法、研究现状、难点及挑战,提出了低成本制备纳米GeO2材料的可行性方案及最新进展。本文为低成本制备纳米GeO2催化材料提供了新的思路,对于促进我国高品质聚酯工业生产的发展具有积极意义。
Nano-GeO2 particles are a major catalyst material for synthesizing high-quality polyesters with excellent optical and aging-resistant performance. Nowadays, there are few reports for its prepa-ration research in China. Domestic enterprises have to import nano-GeO2 powders to meet their production demands. Therefore, the development of inland high-quality polyesters is restricted. In this work, we discussed the catalytic mechanism of polyester synthesis and its current situation, and introduced the advantages of nano-GeO2 served as catalyst. Then, we came up with the appli-cable preparation method of low-cost nano-GeO2 and the latest research advance based on analyzing the previous synthesis methods, research status and fabrication difficulties of nano-GeO2. This paper provides a new idea for the production of low-cost nano-GeO2 catalysts, and may leave a positive impact on the development of domestic high-quality polyesters.
