PLA-PEI is a new type of biodegradable material, which is prepared by coupling reaction of polylactic acid (PLA) and polyetherimide (PEI). This material combines the advantages of PLA biodegradability and PEI high strength and high heat resistance, and has a wide range of application prospects.
PLA is a biodegradable material made from the polymerization of lactic acid, which has good biocompatibility and degradability. However, the relatively poor mechanical properties of PLA limit its application in some fields. PEI is a high-performance engineering plastic with excellent mechanical properties, heat resistance, and electrical insulation properties. However, PEI is not biodegradable and is difficult to meet environmental requirements.
By coupling PLA and PEI, a biodegradable material that combines the advantages of both can be obtained. In PLA-PEI, PLA acts as a biodegradable part to ensure the degradability of the material;As a reinforcing part, PEI can improve the mechanical properties and heat resistance of the material. The preparation methods of this material include melt blending, chemical coupling, etc.
