一般描述

硅胶是胶体二氧化硅的刚性3D网络结构。它专门用作Ziegler-Natta催化剂中活性钛（III）中心的载体材料。硅胶可实现控制破碎，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 - 孔内充满水
b.干凝胶 - 通过蒸发过程，去除孔中的水相。
c.气凝胶 - 通过超临界萃取去除溶剂

应用

硅胶被用于比较MCM-41型中孔吸附剂。

附注

推荐应用
923级符合ASTM D1319碳氢化合物分析规范

Herring roe oil supplementation alters microglial cell gene expression and reduces peripheral inflammation after immune activation in a neonatal piglet model.

Megan P Caputo et al.

Brain, behavior, and immunity, 81, 455-469 (2019-07-05)

Neonatal brain development can be disrupted by infection that results in microglial cell activation and neuroinflammation. Studies indicate that polyunsaturated fatty acids (PUFAs) and their metabolites can resolve inflammation. It is not known if dietary PUFA increases lipid metabolites in

Dissipative water intrusion in hydrophobic MCM-41 type materials.

T Martin et al.

Chemical communications (Cambridge, England), (1)(1), 24-25 (2002-07-18)

Texture-related features of water intrusion in hydrophobised MCM-41 silicas render these materials especially suitable for energy dissipation in mechanical dampers.
