The present invention discloses a PLA/PBS compatibilizer, its preparation method and application, belonging to the technical field of biodegradable polymer materials. In the present invention, PLA and PBS are used as raw materials, peroxide as an initiator, and a twin-screw extruder is used to prepare the compatibilizer PLA‑g‑PBS. The grafting ratio of the prepared compatibilizer PLA‑g‑PBS is as high as 80%. When added into the PLA/PBS blend alloy system, the compatibilizer PLA‑g‑PBS acts as an intermediate phase, improves the interfacial adhesion between the PLA phase and the PBS phase, enhances the interaction force between the two phases and improves the compatibility, and also improves the mechanical properties of the PLA/PBS blend alloy. The raw materials required for the compatibilizer PLA‑g‑PBS prepared by the present invention are easily available, the process is simple, and it is easy for large-scale industrial production.
