摘要

可生物降解聚合物因其主链可通过化学或生物过程实现可控裂解，为废弃塑料的终端处置提供了多样化且环境友好的解决方案，在推动可持续的循环塑料经济发展中具有广阔前景. 然而，该类材料在加工性与力学性能方面的局限长期制约着其大规模应用. 近年来，通过在聚合物网络中引入动态键合相互作用，为可生物降解聚合物的性能优化与高效回收提供了新途径. 动态交联策略不仅可以改善材料的加工流动性能、力学性能和界面相互作用，还可显著提升其循环利用潜力. 本文系统综述了基于动态网络策略在调控可生物降解聚合物的加工行为(如可生物降解聚酯的拉伸流动特性与天然多糖高分子的热塑性成型)、增强力学性能、改善多相/复合体系界面相互作用以及实现高效回收与再利用方面的研究进展，并对该领域未来面临的挑战与发展方向进行了展望.

Abstract

Biodegradable polymers have garnered significant attention due to the controllable cleavage of their backbone

via

chemical or biological processes

offering diverse and env

ironmentally friendly end-of-life management options for plastic waste

and holding great promise for advancing a sustainable circular plastics economy. However

the widespread application of these materials has long been hindered by limitations in their processability and mechanical properties. In recent years

the introduction of dynamic bonding interactions into polymer networks has opened new avenues for enhancing the performance and recyclability of biodegradable polymers. Dynamic cross-linking strategies have not only improved processability

mechanical properties

and interfacial compatibility but have also significantly increased their potential for closed-loop recycling. This review systematically summarizes recent advances in dynamic network strategies for regulating processing behavior (such as extensional flow properties of biodegradable polyesters and thermoplastic processing of natural polysaccharides)

enhancing mechanical performance

optimizing interfacial interactions in multiphase/composite systems

as well as enabling efficient recycling and reuse of biodegradable polymers. Finally

current challenges and future perspectives and challenges in this emerging field are discussed.
