| 摘 要： | 采用浸渍法在二氧化硅多孔材料中负载壳聚糖制备壳聚糖/SiO2复合材料，通过X射线衍射、扫描电子显微镜、傅立叶变换红外光谱等方法对所制备材料的组成与结构进行了表征，采用热重-差示扫描量热法研究了复合材料的热稳定性，采用电流中断法测定所制备材料的电导率来衡量其质子传导性能，并考察了壳聚糖溶液浓度对壳聚糖/SiO2复合材料导电性能的影响。结果表明，壳聚糖/SiO2复合材料具有较高的热稳定性，复合材料的电导率随着壳聚糖乙酸溶液浓度的增加而增加，当壳聚糖乙酸溶液质量百分比浓度为2.5%时,电导率可达1.82 S/cm。

| Abstract: | The chitosan/SiO2 composites were prepared by impregnating chitosan into porous silica matrix. The composition and structure of as-prepared samples were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM) and Fourier transform infrared spectroscopy(FIIR). The thermal stability of the composites was studied by thermogravimetry-differential scanning calorimetry(TG-DSC), and the proton conductivity of the composites was measured by the current interruption method. The effects of the concentration of chitosan solution on the conductivity of the chitosan/SiO2 composites were also investigated. The results indicate that the chitosan/SiO2 composites exhibit higher thermal stability. Moreover, the proton conductivity of the composites increases with the concentration of chitosan-acctic acid solution, and the proton conductivity reaches 1.82S/cm when the concentration of chitosan solution is 2.5%(wt). |
