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.
