Abstract

A number of separation methods were applied to wash and disperse SiO 2-coated Ag (Ag/SiO 2) nanocomposites in order to establish the best practical protocol for producing stable dispersions. Colloidal stability and degree of aggregation for the resulting nanodispersions were assessed. The results show that high-performance liquid chromatography is an enabling technique for a well-dispersed suspension of Ag/SiO 2 nanocomposite particulates. The nanoparticle dispersion technique is based on a size-exclusion chromatography principle that can be extended to other nanoparticles.
