General description
硅胶是胶体二氧化硅的刚性三维网络。它专门用作齐格勒-纳塔催化剂中活性钛(III)中心的载体材料。硅胶允许受控的碎裂,导致形成具有窄粒度分布和高堆积密度的均匀聚合物颗粒。硅胶分类如下:
a.水凝胶 - 孔内充满了水
b.干凝胶 - 通过蒸发过程,气孔中的水相被去除
c.气凝胶 - 通过超临界萃取去除溶剂

In this report, procedures are discussed for the enrichment of single-walled carbon nanotube (SWNT) types by simple filtration of the functionalized SWNTs through silica gel. This separation uses nanotube sidewall functionalization employing two different strategies. In the first approach, a
