Effect of Surfactants on the Synthesis of Monodisperse Silica Spheres

Abstract:

In this work, the influence of surfactant including the amount and the nature of the surfactant as well as alcohol solvents with different hydrocarbon chains including methanol, ethanol, 1-propanol and n-butanol on the formation of silica spheres were investigated. The morphologies and the composition of the prepared silica spheres were studied with scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) techniques. The results revealed that the size and size distribution of the spheres can be modified by changing the concentration or the nature of the surfactant additives. The influence mechanisms of surfactants additives and the alcohol solvent on the formation of silica spheres were discussed based on nucleation and growing process of the spheres.
