The stucture of bioplastic from cassava starch with nanoclay reinforcement

Abstract

Biocomposite plastics are plasticts that will decompose in nature with the assistance of microorganism. Cassava starch as the main material of plastic has great potential in Indonesia because this plant there are different starch crops. The objective of this research was to determine the effect of nanoclay on the physical structure using XRD. The results showed that the concentration of cassava starch with the best physical and mechanical properties is 5,0% (b/v) and glycerol 1,5% (v/v). XRD analysis show that the structure of bioplastic with nanoclay reinforcement have peak in 2θ were about 16.8°, 19.8°. After bioplastic was reinforced by nanoclay, structure of bioplastic change with shitf of peak angle to about 2θ of 17.4° and 20.1°.
