Abstract

Aerogel is a kind of gel materials, of which the fluid phase is gas. Aerogel has the characteristics of low density and high porosity, and has a wide application prospects. In this work, a rapid solvents exchange method was developed, and using in-situ secondary extraction, rapid solvents exchange in aerogel preparation was achieved through the miscibility and immiscibility of ethanol-dichloromethane-water. Combined with hydrophobic treatment and vacuum drying, hydrophobic silica aerogel was obtained. The aerogel had a low density and a contact angle with water of 155.8°. The aerogel can load various organic fluorescent probe dyes, which can effectively avoid the fluorescence quenching caused by the aggregation of the probe molecules, which it will expand the practical application range of the organic fluorescent probes in wider fields.
