ABSTRACT

In this chapter, aerogel particles are prepared from W/O lotion, the emulsification mechanism of lotion is briefly described, and the factors affecting the preparation of aerogel microspheres are studied. Through a series of characterization and tests, it is known that: properly increasing the temperature can accelerate the gel reaction rate and shorten the gel time; The stirring rate and surface modifier have certain effects on the density and porosity of aerogel. The preparation of silicon aerogel by lotion method reduces the tedious steps of solvent replacement, shortens the preparation cycle, and greatly reduces the preparation cost.
