Synthesis of thermal and chemical resistant oxygen barrier starch with reinforcement of nano silicon carbide

•The structure of the starch/SiC bionanocomposites was studied by XRD and FESEM.•Thermal resistance of starch was enhanced due to dispersion of nano SiC.•Permeability was reduced significantly as compared to the virgin starch. Starch/silicon carbide (starch/SiC) bionanocomposites were synthesized by solution method using different wt% of silicon carbide with starch matrix. The interaction between starch and silicon carbide was studied by Fourier transform infrared (FTIR) spectroscopy. The structure of the bionanocomposites was investigated by X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM). Thermal property of starch/SiC bionanocomposites was measured and a significant enhancement of thermal resistance was noticed. The oxygen barrier property of the composites was studied and a substantial reduction in permeability was observed as compared to the virgin starch. The reduction of oxygen permeability with enhancement of thermal stability of prepared bionanocomposites may enable the materials suitable for thermal resistant packaging and adhesive applications.
