Description

technical field

[0001] The invention relates to a high-performance composite material and a preparation method thereof, belonging to the technical field of polymer processing and modification. Background technique

[0002] Due to the increasingly prominent problems of shortage of petroleum resources and serious environmental pollution, environmentally friendly materials are increasingly favored by people. Polylactic acid (PLA) is a bio-based and biodegradable material, and its synthetic raw materials are derived from plant resources such as corn, which are abundant and renewable. In addition, polylactic acid also has good biocompatibility, processability and mechanical strength, and is an ideal green polymer material. Polylactic acid (PLA) includes L-polylactic acid (PLLA), D-polylactic acid (PDLA) and racemic polylactic acid (PDLLA). PLLA and PDLA have opposite optical activity. When the two are blended, there will be structural complementarity between the molecular chain...
