Research and Application Progress of Bio-based Closed-loop Recyclable Polymers

Using renewable biomass as raw material, designing and synthesizing polymer materials with closed-loop recycling could realize the sustainable development of raw materials and polymer materials. This paper outlined the development and properties of bio-based closed-loop recyclable polymer materials, and introduced the research progress of bio-based closed-loop recyclable polymer materials such as lignin, cellulose and vegetable oil in recent years from the aspects of design, synthesis, performance and applications. The current status of their applications in 3D printing, flexible electronic materials, triboelectric nanogenerators, antimicrobial materials, solar energy evaporators were summarized. And suggestions for the future research of bio-based closed-loop recyclable polymer materials were put forward, aiming to bring breakthroughs and innovations to the field of polymer materials and promote their applications and development in various fields.
