ABSTRACT
The morphological, mechanical and physical properties of composites of PLA (Poly Lactic Acid) with or without MPLA (maleic anhydride (MAH)-modified-PLA) compatibilizer under various filler types and testing conditions had been studied. The tensile properties of the composites varied with the filler types. The tensile properties of the composites with Cellulose Powder (CP) based filler are greater than those with WF (Wood Flour) and CS (Corn Starch) based fillers. The order is CP>WF>CS. The Scanning Electron Microscopy (SEM) showed that addition of MPLA compatibilizer to the composites improved the dispersion and the adhesion of the filler and the matrix. It was found that after immersion in cold water for 24 h and drying at 60°C for 7 days or 105°C for 3 days, the tensile properties of the composites based on CP and WF fillers were unchanged. The composites based on CP and WF fillers were more resistant to water than the CS-filled composite. After storage in a room adjusted to 20°C and 60% R.H. for 3 months, the Moisture Content (MC) of the composites with CP/WF/CS fillers was less than 6%. The CP and WF-filled composites with MPLA compatibilizer tended to give lower MC than compatibilizer-free composites.
