Eco-Synthesis of Hollow Silica Nanoparticles and their Application

Abstract

Hollow silica nanoparticles (HSNPs) are the solid-gas composite particle which consist of an air cavity surrounded by a silica shell. With this abnormal structure, HSNPs show superior properties compared to dense silica particles. For application of the properties, the HSNPs must be dispersed in the final production medium such as a film. In one interesting application, HSNPs can be applicated as anti-slip materials against sweat, and volleyballs coated with HSNPs were used as the official balls at the Beijing Olympics. In this paper, the synthesis method, dispersion technique for application and the application of HSNPs are described.
