| Abstract: | Polybutylene succinate/micro-fibrillated cellulose composites with high performance are prepared by solid-state hot stretching, and the effect of structure, interfacial adhesion and lamellar orientation on the mechanical property of the composites are investigated. The interfacial crystallization around the fiber during processing has improved the interfacial adhesion of composites. Additionally, stretching has facilitated the orientation of cellulose and polybutylene succinate lamellar, which has further improved the mechanical property of composites. This process is simple, easy to operate and available for various polymers, which is beneficial for inspiring students to flexibly use various polymer processing methods to prepare high-performance composites. |
