摘要
文章主要介绍了通过在硅溶胶体系的凝胶过程中添加干燥控制化学添加剂(DCCA),并利用非超临界干燥技术制备硅气凝胶,研究了DCCA对凝胶过程及凝胶产品的品质影响,以及不同的DCCA对凝胶品质的影响。
Silica aegrogels were prepared through the gelation process of solica sol systems in which drying control chemical additives（DCCAs）were added,followed by non-supercritical drying.The effect of DCCAs on the gelation process and qualities of resulting aerogels was also investigated.Different relationships of the variation of aerogels’ properties with DCCAs.
