Abstract
Composite particles are formed using negative and amphoteric monodispersed latices as the core and shell respectively, and the experimental conditions to obtain maximum coverage of the surface of core particles with amphoteric particles and the mechanism of the deposition process are investigated. As results, (1) the experimental conditions for forming the composite particles are clarified; (2) the maximum coverage of the core surface with amphoteric particles is found not to be greater than 0.3; and (3) the coverage is mainly determined by the strength of the repulsive force between deposited particles. The relation between the coverage and the zeta potential of composite particles is also clarified.
