To enhance the interfacial compatibility between bamboo fiber (BF) and polylactic acid(PLA)
the copolymer of PLA grafted with glycidyl methacrylate (GMA-g-PLA
GPLA) was synthesized by melt grafting approach using dicumyl peroxide as initiator
the influences of GPLA addition on the interfacial morphology and properties of BF/PLA composites were investigated
and the interfacial compatibilization effect of GPLA was compared with silane coupling agent(KH550) and MDI. The result showed that
the GPLA showed great interfacial compatibilization and properties improvement for the BF/PLA composites
which was much better than the compatibilization efficiency by using MDI or KH550. The BF/PLA composites with 16% mass fraction of GPLA (towards the composites) provided the optimum properties
with an improvement of 72. 10% in tensile strength
118. 1% in flexural strength
81. 6% in notched impact strength
200% in elongation at break and 28. 39% in vicat softing point respectively
and a decrease of 31. 6% in water adsorption compared with those without GPLA.
