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.
采用溶液法合成了不同质量分数碳化硅/淀粉（starch/SiC）纳米复合材料，以淀粉为基体。通过傅里叶变换红外光谱（FTIR）研究了淀粉与碳化硅之间的相互作用。采用 X 射线衍射（XRD）和场发射扫描电子显微镜（FESEM）研究了纳米复合材料的结构。对淀粉/SiC 纳米复合材料的热性能进行了测试，发现其耐热性能有显著提高。研究了复合材料的氧气阻隔性能，发现与原始淀粉相比，其渗透性有显著降低。制备的纳米复合材料的氧气透过率降低和热稳定性提高，可能使这些材料适用于耐热包装和胶粘剂应用。
