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 sheets by compression molding. The mixing ratio of
TPS/RPET was fixed at 30/70 wt%, while HMDI was added at 5 wt% based on starch content.
Biochar contents were varied from 10 to 40 wt%. The results showed that the presence of
5 wt% HMDI led to improvement of mechanical and thermal properties of TPS/RPET
compound which resulted in 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 30 TPS/RPET when compared to other biochar contents because of its better
dispersion in RPET matrix. In addition, biochar could improve thermal stability of
30 TPS/RPET biocomposite. Besides, the water absorption ability of TPS/RPET/biochar
composite increased with an increase in TPS and biochar. On the other hand, the presence of
HMDI led to the diminishing of water absorption ability of TPS/RPET/biochar biocomposite.
