1. Introduction In recent years, nano-particles have received considerable attention for their special physical and chemical properties. However, inorganic nano-particles are very prone to agglomerate in media and show poor dispersion capacity in organic solvents and oil due to their high surface energy. Because of the inconsistent interfacial interaction, the combination of the inorganic nano-particles […]
