The adsorption of the copolymer on Y\|TZP powder was characterized by using the COD(chemical oxygen demand) method. The addition of this dispersant caused a dramatic increase of the \%ζ\% potential in alkaline region and broadened the stable pH region. SEM and effective diameter analysis showed that the copolymer pronouncedly improved the stability of the suspension. The force\|distance curve was measured by using the colloidal probe AFM method. The stabilizing mechanism of the dispersant was also discussed.展开更多
