POLYLACTIDE COMPOSITES FILLED WITH MICROCRYSTALLINE CELLULOSE, NANOCRYSTALLINE CELLULOSE AND CELLULOSE NANOFIBERS

摘要

Polylactide (PLA) nanocomposites based on microcrystalline cellulose (MCC), nanocrystalline cellulose (NCC) and cellulose nanofibers (CNF) were prepared in the molten state by rnicroextrusion. The dispersion was investigated by optical and electron microscopy. The mechanical properties of the nanocomposites were analyzed by dynamic mechanical analysis (DMA). The thermal properties were analyzed by differential scanning calorimetry (DSC). The effect of the addition of a proper coupling agent on dispersion and mechanical properties was analyzed.
