Disperse SiO₂ Nanoparticles in Nonaqueous Solvents by Shear Emulsification and Surface Functionalization

Abstract:

Spheric SiO₂ nanoparticles with the sizes distribution between 20-80 nm dispersed in nonaqueous solvent were prepared under the assistance of surfactant. Shear emulsification time was a key role for the dispersion of nanoparticles and the optimal value was 30 min with the smallest median size of 51 nm. The relationship between fluid viscosity and dispersion condition was researched, and the results demonstrated that the additional volume arising from aggregation interspaces enhanced shear fore and opposite resistance and finally the viscosity increased.
