Abstract

Abstract

Spheric SiO2 nanoparticles with the sizes range in 10-100 nm are dispersed in nonaqueous solvent under the assistant of surfactant. Hydrogen bond bridge effect and long chain molecule spatial hindrance are two key roles for dispersion. The particles median size is 30.2 nm according to dynamic light scattering (DLS) test and exhibits nice agreement with transmission electron microscopy(TEM) result under optimal surfactant volume ratio of 6%.
