摘要
塑料的优越性能使其广泛应用于人们的衣、食、住、行。然而，大量积存的无法分解的塑料垃圾对环境造成了负面影响。聚对苯二甲酸乙二醇酯（PET）自 1941 年投放市场以来，已广泛应用于工业和家庭。由于分子链中酯基的相对活性，为 PET 的降解性提供了无限潜力。本文以 PET 为例，介绍了目前常见的 PET 回收和解聚工艺，阐述了各种方法的反应机理，并展望了解决 PET 污染问题的未来发展趋势。
Recycling and depolymerisation of poly(ethylene terephthalate): a review
The superior properties of plastic have led to its widespread use in people's clothing, food, housing and transportation. However, the large amount of accumulated plastic waste that cannot be deconstructed has a negative impact on the environment. Poly(ethylene terephthalate) (PET), since its introduction to the market in 1941, has been widely used in industry and households. Due to the relative activity of the ester group in the molecular chain, it provides unlimited potential for the degradability of PET. This article takes PET as an example, introduces the current common processes of PET recycling and depolymerisation, elaborates on the reaction mechanisms of various methods, and looks forward to the future development trend of solving the problem of PET pollution.
期刊介绍：
Polymer Chemistry welcomes submissions in all areas of polymer science that have a strong focus on macromolecular chemistry. Manuscripts may cover a broad range of fields, yet no direct application focus is required.
