Eco-Friendly Fabrication of Highly Stable Silica Aerogel Microspheres with Core-Shell Structure.

Silica aerogel microspheres show great potential in various fields as fillings in different materials. It is important to diversify and optimize the fabrication methodology for silica aerogel microspheres (SAMS). This paper presents an eco-friendly synthetic technique for producing functional silica aerogel microspheres with a core-shell structure.
