영문 초록

Poly(lactic acid) (PLA) was first melt-compounded with wood flour (WF) to produce PLA and PLA/WF biocomposites using twin screw extruder. In order to improve performances further, maleic anhydride grafted styrene-ethylene-butylene-styrene (MASEBS) and nanoclay (NC) were added as a master-batch (MASEBS-NC). This study investigated the effect of MASEBS-NC on the mechanical, thermal and morphological properties of PLA and PLA/WF biocomposites. The incorporation of MASEBS-NC to PLA and PLA/WF biocomposites improved ductility and overall impact strength, but reduced flexural properties. The presence of MASEBS-NC in PLA and PLA/WF biocomposites enhanced the thermal stability by synergistic effect of MASEBS and NC. Morphological properties showed that good interfacial bonding between PLA and WF was achieved by the incorporation of MASEBS-NC. As a results of this study, it seems that the MASEBS-NC in the PLA and PLA/WF biocomposites effectively performed its role as func-tional filler and coupling agent.
