| 摘 要： | 以壳聚糖和无机铝盐AlCl3.6H2O为原料,通过溶胶-凝胶方法,分别用CO2超临界干燥手段及冷冻干燥手段制备了新型的壳聚糖/氧化铝复合气凝胶.结果表明,壳聚糖的含量影响复合气凝胶的比表面积及孔体积等性质,随着壳聚糖含量的增加,混合气凝胶的比表面积逐渐减小.不同的干燥方法对复合气凝胶的比表面积等性质也有明显的影响.

| Abstract: | New chitosan/Al2O3 hybrid aerogels were prepared by the sol-gel route with supercritical carbon dioxide(CO2) drying and freeze drying from its corresponding wet-gels.The resulting materials were characterized using nitrogen adsorption/desorption analysis.The results show that both drying methods and contents of chitosan take obvious effect on the textural characteristics of the prepared aerogels. |
