| 摘 要： | 以壳聚糖作为模板剂,氯化锌作为前驱物通过溶胶-凝胶法制备出湿凝胶,经二氧化碳超临界干燥得到掺锌壳聚糖气凝胶。通过场发射扫描电镜(FESEM)和N2吸/脱附测试对气凝胶的微观结构和性能进行了表征。结果表明:掺锌壳聚糖气凝胶具有明显的三维纳米多孔结构;壳聚糖的含量对气凝胶的微观结构影响明显;当m(壳聚糖)∶m(氯化锌)=1∶1时,气凝胶骨架纤细,比表面积460 m2/g,平均孔径分布在3～10 nm。

| Abstract: | In this study, we developed the innovation of Zn-doped Chitosan aerogel using Chitosan as template and ZnCl2 as precursor, which employed the properties of three-dimensional porous structure. By adopting field-emmision scanning electron microscope (FESEM) and N2 adsorption/desorption, we learn that the Zn-doped Chitosan aerogels have three-dimensional porous structures featuring high surface area. When the mass ratio of Chitosan to ZnCl2 is 1:1, the measurements show that the aerogel has high BET surface area of 460 m²/g, average pore diameter about 3~10nm, which means the aerogel possesses the typical characteristic of porous. |
