| Abstract: | PLA/esterified cellulose/CaCO3 composites were prepared by melt blending technology.The effect of CaCO3 on mechanical properties and thermal stability of the composite was investigated by means of mechanical properties testing,TGA,GPC,and FTIR.The results indicate that the interaction between CaCO3 and esterified cellulose improves the mechanical properties and thermal stability of the composites,and is helpful to prevent the thermal degradation of PLA. |
