Control of Dispersion and Particle Assembling Structures in Non-aqueous, Dense, and Multicomponent Slurries

Abstract

Our recent study on design of partial complex of polyethyleneimine and fatty acids/anionic surfactants toward dispersion stability control of non-aqueous, dense, and multicomponent slurries were reviewed. A series of polyethyleneimine complex were successfully designed by simple mixing process and found to effectively adsorb on many species of particles which lead to stability improvement of non-aqueous, dense, multicomponent slurries. A simple elaboration in the mixing orders of powders, solvents, and polyethyleneimine complex also found to compatibly realize the particle assembling and dispersion improvements. An example for applying these dispersion/particle assembling techniques to microstructure design of ceramic green parts will also introduced.
