Abstract
Starch as biopolymer from nature consist of amylose and amylopectin. Most starch based composites exhibit poor material properties such as tensile strength, stiffness and elongation at break. The addition of plasticizers to starch films increase the mobility of polymer chains, decrease its inherent brittleness by reducing intermolecular forces and its glass transition temperature so improve their flexibility. Beside plasticized the tapioca starch need to be filled by fiber and mineral as reinforcement improve the properties. The thermal stability of tapioca starch could be carried out by TGA analysis to measure the amount and rate of change in weight of the material. Through hydrogen bondings, the possible interaction between the tapioca starch, plasticizer and filler could be seen by FTIR analysis by quantisized molecular resonances that absorb electromagnetic energy broadband infrared source obtained from spectra.
