AI Article Synopsis
- Researchers developed a biodegradable and recyclable bio-based plastic using carboxymethyl cellulose (CMC) and cationic polymeric ionic liquid (PILCl) to address environmental issues caused by traditional plastics.
- The resulting CMC/PIL plastic film boasts impressive mechanical properties, with a tensile strength of around 200 MPa, and retains almost the same strength even after recycling.
- This new type of plastic can be shaped into 3D forms using water, maintains its properties through multiple formations, and biodegrades rapidly in soil or with cellulase enzymes.
Article Abstract
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.
