Convenient Preparation of Superhhydrophobic Ormosil Powder

Baiyu Li, Xiaogang Gao, Zaiman Liu
Methyltrimethoxysilane (MTMS) was used as the precursor to prepare organically modified silica (ormosil) aerogel powder. The preparation was done in two steps. In the first step, MTMS was transformed into a gel through crosslinking by a small amount of sodium silicate, and the gel was broken into small...
