Mechanical and Thermal Properties of Thermoplastic Film from <i>Tacca leontopetaloides</i> Starch Reinforced with Rice Husk Biochar

Abstract

The objective of this study is to investigate the mechanical and thermal properties of thermoplastic film (TPS) from Taccaleontopetaloides starch. T.leontopetaloides was opted as starch source due to its abundance in nature, cheap and non-staple food in Malaysia. Biochar from rice husk was incorporated with T. leontopetaloides starch as a novel idea to enhance the properties of the thermoplastic film and solving the agricultural waste disposal problem. The TPSs were developed through solution casting method. Incorporation of biochar into TPS (TPS-BChr) composite significantly improved the tensile strength and elongation at break (EAB) properties of TPS. Thermal analysis showed that TPS10%-BChr composite had the highest maximum degradation temperature and the highest amount of residue (23.94%) compared to other TPS’s compositions. These results showed that incorporation of biochar into TPS significantly improved the mechanical and thermal properties of the TPS.

The Effect of Red Palm Oil Concentration towards Characteristics and Biodegradability of PLA-Starch Film

“…Theoretically, increase of tensile strength will decrease the elongation at break point. This is greatly opposite with the result by previous researchers [20][21]. According to Chieng et al pure PLA typically rigid and brittle.…”
