“…In general, the preparation methods of silica aerogels include the sol-gel method and hydrothermal method. The sol-gel method refers to a method where inorganic compounds are hydrolyzed and condensed in a solution to form a gel with a spatial network structure and porous structural materials are obtained after removing the solvent [ 1 ]. The process of preparing aerogels by this method includes hydrolysis, drying, solvent replacement, atmospheric pressure drying, etc.…”

Using silica as the precursor, and methyltrimethoxysilane and dimethyldimethoxysilane as the silicon sources, a super-flexible hydrophobic lipophilic gel solid was prepared via hydrolysis, drying, solvent replacement, and atmospheric-pressure drying. The characterization test showed that the sample had good flexibility, hydrophobicity, an amorphous structure, and a hydrophobic contact angle of 137°. Through the adsorption separation experiment, it was concluded that the adsorption separation rate of aerogel to oil substances is related to the viscosity of the oil substances. The hydrophobic and oleophilic properties of flexible silicon aerogel materials can be applied to many aspects, such as crude oil leakage and kitchen waste oil recovery, with broad future development prospects and great research significance.
