13 Effect of sugarcane bagasse on thermal and mechanical properties of thermoplastic cassava starch/beeswax composites

Abstract
The demand for biodegradable material has been an important issue, especially in food packaging applications. Among many biodegradable materials, starch biopolymer has been recognised as a completely biodegradable material that can be produced from various plants. It is one of the richest resources that are renewable, biodegradable, and available at low cost. However, starch biopolymers are often associated with poor mechanical properties. Hence, the main objective of this study is to evaluate the mechanical and thermal characteristics of sugarcane bagasse fibre (SBF) reinforced thermoplastic cassava starch (TPCS), which was prior modified with beeswax (BW). It was found that the mechanical properties such as tensile, flexural, and impact strength have improved significantly with the incorporation of SBF loading into the TPCS/BW matrix. The highest tensile strength (12.2 MPa) and modulus (2222.6 MPa) were exhibit by sample with 20 wt% SBF loading and further increment of fibre led to decrease in the strength of the materials. The thermal properties showed that higher SBF loading resulted in improved thermal stability of the material, i.e., higher glass transition and melting temperature than the polymer matrix. Overall, SBF has shown good potential as a reinforcing material which is able to improve the functional characteristics of TPCS/BW as a new potential biodegradable material.
