摘要
综述了近年来国内外废PET聚酯化学解聚法的研究进展,包括传统化学解聚法和新型化学解聚法,重点论述了新型化学解聚法,包括微波辅助解聚法、超/亚临界解聚法、离子液体解聚法和酶催化解聚法等,分析对比了各自的优缺点,同时介绍了废PET解聚后的功能化应用,指明开发高效解聚催化剂和PET功能化应用是废PET聚酯的今后发展方向。
The research progresses in chemical depolymerization for waste polyesters(PET)at home and abroad in recent years are reviewed,including the traditional chemical depolymerization processes and new chemical depolymerization processes.The new microwave assisted depolymerization processes,super/subcritical depolymerization processes,ionic liquid depolymerization processes and enzymatic depolymerization processes are focused on.The advantages and disadvantages of these methods are analyzed and compared.At the same time,the functional applications of waste PET after depolymerization are introduced.The future development trends are pointed out,which are the development of high-efficiency depolymerization catalysts and PET functional applications.
