Polymeric materials play a pivotal role in our modern world, offering a diverse range of applications. However, they have been designed with end-properties in mind over recyclability, leading to a crisis in their waste management. The recent emergence of electrochemical recycling methodologies for polymeric materials provides new perspectives on closing their life cycle, and to a larger extent, the plastic loop by transforming plastic waste into monomers, building blocks, or new polymers. In this context, we summarize electrochemical strategies developed for the recovery of building blocks, the functionalization of polymer chains as well as paired electrolysis and discuss how they can make an impact on plastic recycling, especially compared to traditional thermochemical approaches. Additionally, we explore potential directions that could revolutionize research in electrochemical plastic recycling, addressing associated challenges.
高分子材料在我们的现代世界中发挥着关键作用,具有广泛的应用。然而,它们在设计时更多地考虑最终性能而非可回收性,导致其废物管理面临危机。最近出现的用于高分子材料的电化学回收方法为闭合其生命周期提供了新视角,并且在很大程度上通过将塑料废物转化为单体、结构单元或新聚合物来闭合塑料循环。在此背景下,我们总结了为回收结构单元、聚合物链功能化以及成对电解而开发的电化学策略,并讨论它们如何对塑料回收产生影响,特别是与传统热化学方法相比。此外,我们探索了可能彻底改变电化学塑料回收研究的潜在方向,并应对相关挑战。
