Currently, there is increasing interest in using biodegradable and renewable materials for disposable applications as an alternative of some conventional petroleum plastics. Cellulose ester, particularly preferable for a liquid crystal display device, is prepared from the esterification of cellulose derived from abundant plant. Poly(lactic acid) (PLA) is a promising synthetic biopolymer derived from agricultural feedstock, but it has poor thermal and mechanical properties. In this work, Poly(lactic acid) (PLA) and Cellulose acetate butyrate (CAB) were melt blended using twin screw extruder in order to improve properties of bio-based polymer and to expand applications. The phase morphology of PLA/CAB alloys was investigated by Scanning Electronic Microscopy (SEM). The compatibility of alloys was analyzed by Fourier-Transformation Infrared (FT-IR) and Dynamic Mechanical Analyzer (DMA). |
