Preparation of Biocomposite from Recycled PET Bottle and Starch Reinforced with Biochar from Durian Peels
Main Article Content
Abstract
This research focuses on the preparation of biodegradable films from recycled polyethylene terephthalate (RPET) and thermoplastic starch (TPS) reinforced with biochar from durian peels. In this study, hexamethylene diisocyanate (HMDI) was used as a compatibilizer and the influences of biochar contents on physical properties, morphology, mechanical properties, thermal properties and water absorption ability of biocomposite films were studied. For biocomposite preparation, all ingredients, i.e. TPS, RPET biochar and HMDI were mixed by internal mixer and fabricated into thin sheet by compression molding. The mixing ratio of TPS/RPET was fixed at 30/70 wt%, while HMDI was added at 5wt% based on starch content. Biochar contents were varied from 10 to 40 wt%. The results showed that the presence of 5wt% HMDI led to improvement of mechanical and thermal properties of TPS/RPET compound which resulted from the improvement of interfacial adhesion between RPET and TPS. Moreover, the addition of 20 wt% biochar resulted in the highest flexural strength and flexural modulus of 30TPS/RPET when compare to other biochar contents because of its better dispersion in RPET matrix. In addition, biochar could improve thermal stability of 30TPS/RPET biocomposite. Besides, the water absorption ability of TPS/RPET/biochar composite was increased when TPS and biochar increased. On the other hand, the presence of HMDI led to the diminish of water absorption ability of TPS/RPET/biochar biocomposite.
