The fabrication of biodegradable and recyclable bio-based plastic by complexing carboxymethyl cellulose (CMC) and cationic polymeric ionic liquid (PILCl) assisted with KNO is offered to utilize plastics sustainably and mitigate serious threats to the environment. The CMC/PIL plastic film, formed via electrostatic interactions, exhibits exceptional mechanical properties that surpass those of most conventional plastics. It demonstrates a tensile strength of approximately 200 MPa and a Young's modulus of around 5.5GPa. Even after recycling and regeneration, they essentially retain the original mechanical characteristics with a tensile strength of about 190 MPa. These CMC/PIL plastic films can be processed into three-dimensional (3D) shapes assisted with water and their fundamental qualities maintain after numerous shaping. Besides, they possess excellent biodegradability and can finish biodegrading in a few hours with cellulase and within a few days when exposed to soil. This innovation provides a fresh and practical way to produce degradable plastics.
通过络合羧甲基纤维素（CMC）和阳离子聚合离子液体（PILCl）并借助KNO制备可生物降解和可回收的生物基塑料，以实现塑料的可持续利用并减轻对环境的严重威胁。通过静电相互作用形成的CMC/PIL塑料薄膜具有卓越的机械性能，超过了大多数传统塑料。它的拉伸强度约为200MPa，杨氏模量约为5.5GPa。即使经过回收和再生，它们基本上仍保留原始机械特性，拉伸强度约为190MPa。这些CMC/PIL塑料薄膜在水的辅助下可加工成三维（3D）形状，并且在多次成型后其基本质量得以保持。此外，它们具有出色的生物降解性，在纤维素酶作用下几小时内即可完成生物降解，暴露在土壤中几天内也可降解。这项创新为生产可降解塑料提供了一种新颖且实用的方法。
