摘要: Polylactide (PLA) composites with 10–30 wt% of commercial fine grain filler native cellulose were prepared by melt-mixing, and examined. The composite films had esthetic appearance, glossy surface, creamy color density close to that neat PLA. Good dispersion the filler in PLA matrix was achieved. stiffer than PLA; glassy region storage modulus increased approx. 30 %. tensile strength materials temperature range from 25 45 °C similar No marked decrease molar mass occurred during processing comparison Moreover, thermogravimetry experiments demonstrated good thermal stability composites; 5 % weight loss well above 300 °C.
