Thermal and Mechanical Properties of Bagasse Microcrystalline Cellulose Reinforced PLA Composites

Abstract:

The biodegradable composite films were prepared from bagasse microcrystalline cellulose as filler and polylactic acid (PLA) as polymeric matrix. The crystallinity, the tensile properties and the thermal properties of the composites were tested. The results show that the tensile properties and thermal properties were improved with the addition of bagasse microcrystalline cellulose. When bagasse microcrystalline cellulose mass fraction was 5%, the initial decomposition temperature was raised by 30.73°C, and the tensile strength increased by 50.98%, and the elongation at break increased by 16.25% compared to those of pure PLA.
