Abstract

Polyethylene terephthalate (PET), the most widely used polyester, is extensively employed in packaging and textiles. However, the inherent complexity of PET waste streams lead to low recycling rate. Chemical recycling offers a promising solution to restore the wastes to monomers or convert them into high-value products. This review summarizes the recent advances on chemical recycling of PET, focusing on enhanced depolymerization strategies throughout the whole reaction system including solvent effect, catalytic effect and energy input mode. The enhancement mechanism is described. In addition, consideration on recycling of PET blends is demonstrated. An outlook for further advances on chemical recycling of PET is proposed.

聚对苯二甲酸乙二醇酯及其共混物的化学解聚：提高循环效率的策略

聚对苯二甲酸乙二醇酯（PET）是应用最广泛的聚酯，广泛用于包装和纺织品。然而，PET废物流的固有复杂性导致回收率低。化学回收提供了一个很有前途的解决方案，将废物恢复为单体或将其转化为高价值产品。本文综述了PET化学回收的最新研究进展，重点介绍了溶剂效应、催化效应和能量输入方式等整个反应体系的增强解聚策略。描述了增强机制。此外，还对PET共混物的回收利用进行了探讨。并对PET化学回收的进一步发展进行了展望。
