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.
