Surface Modification of Powder and the Characterization

Abstract

There are many methods for the surface-modification of powder materials to get the high functionality, such as fluidity, dispersibility, and so on. Commonly used coupling agents react with the surface functional group, especially hydroxyl group, through the formation of chemical bonds, and also the many techniques are applied according to the chemical properties of those agents and the powders. In this paper, our research results of some modification techniques using mainly alcohols and silane coupling agents and the surface characterization methods are described including the historical context.
