Abstract

The cluster formation process using two different kinds of sterically stabilized colloidal particles was studied. The first consisted of silica microspheres with octadecyl(c18) chains grafted to their surfaces and the second consisted of non-crosslinked polymethyl methacrylates (PMMA) microspheres. The clusters were stable in water due to reason that the P123 triblock copolymer surfactant that stabilized the hexane-water interfaces adsorbs onto the colloidal clusters and thus prevented cluster-cluster aggregation. The results show that the ultimate cluster configurations are nearly identical for the various systems.
