摘 要：Poly（lactic acid）-based biocomposites were developed with hemp hurd（Cannabis sativa L.） with grafting-based interfacial compatibilization. Poly（lactic acid） was extruded with hemp hurd and glycidyl methacrylate as the polymer/hurd interfacial compatibilizer, and injection molded. Interfacial compatibility between poly（lactic acid） and hemp hurd increased with grafted glycidyl methacrylate in comparison to the non-compatibilized control, as corroborated by scanning electron microscopy fractography and mechanical analysis, which showed increases in the glycidyl methacrylate-grafted 20%（w/w）hemp hurd/poly（lactic acid） biocomposite, retaining 94% of the neat polymer strength, with increases in crystallinity, and showing a range of thermo-mechanical properties desirable for rigid biocomposite applications.
