Abstract

This study presents a novel, bio-based polymer composite derived from tapioca starch and reinforced with jute fibers, designed for non-load bearing structural applications. The developed composite demonstrated significant thermal stability, with a single decomposition reaction observed above 300°C via TGA, surpassing many synthetic polymers. DSC analysis revealed a glass transition temperature (Tg) of 69.55°C and notable thermal energy storage capability. Mechanical characterization, including three-point bending, tensile, and compressive tests, confirmed effective fiber wetting and a tensile strength of 9 MPa for the composite. Furthermore, the composite exhibited mild electrical conductivity of 3.62 × 10−7 S/m. Structural characterizations (SEM, XRD, FTIR) revealed the presence of an N-H bond, a functional group common in conductive polymers, suggesting its potential as a mild conductor. Density functional theory simulations provided further insights into the biopolymer's molecular structure. This research highlights the promising potential of tapioca starch composites for various engineering applications, particularly as sustainable packaging materials.
