用纳米ZnO为原料,以魔芋葡甘聚糖(KGM)为基体,采用共混法制得KGM/ZnO纳米复合物。通过傅立叶红外光谱(FTIR)、热重分析(TG)、透射电镜(TEM)等手段对该体系进行了表征。结果表明:由于纳米ZnO粒子的引入,KGM分子FTIR的某些特征峰的波数发生明显变化;纳米ZnO在复合物中的分散性较好;复合材料的热稳定性高于KGM薄膜;此外,复合材料的力学性能有所提高。
Using nanometer ZnO as raw material and konjac glucomannan (KGM) as matrix, KGM / ZnO nanocomposite was prepared by blending method. The system was characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TG) and transmission electron microscopy (TEM). The results show that due to the introduction of nano-ZnO particles, the wavenumber of some characteristic peaks of KGM FTIR changes obviously. The dispersion of nano-ZnO in the composite is better. The thermal stability of the composite is higher than that of the KGM film. In addition, The mechanical properties of the material have increased.
