A method for improving the performance of PLA/PPC biodegradable materials by using a compatibilizer relates to a method for improving the performance of biodegradable materials. The present invention performs maleic anhydride end-capping treatment on PPC to enhance its thermal stability. Subsequently, the end-capped PPC is uniformly mixed with PLA, compatibilizer, initiator and antioxidant in a predetermined mass ratio. The obtained mixture is put into a twin-screw extruder for melt blending, and then cooled to room temperature to obtain a PLA/PPC blended material. The blended material not only has excellent mechanical properties and optical properties, but also good processability and hydrophobicity. The present invention solves the brittleness problem of PLA materials in the prior art by introducing a PPC component and adding a compatibilizer to improve its mechanical properties and optical properties. It expands the application prospect of PLA-based blended materials and is of great significance to environmental protection and sustainable development.
