Abstract
The rheological behavior and dispersion stability of magnetic powder s uspension were studied. With the aid of hyperdispersants having poly ( epsilon-caprolactone) as solvatable chian, the viscosity of the suspen sion was lowered and the dispersion stability was improved obviously. The effect of the hyperdispersants was the result of both the type of the anchoring group and the molecular weight of the solvable chain. Wh en the molecular weight of the solvatable chain is 700 and the anchori ng group is the mixture of carboxyl and tertiary amine, the hyperdispe rsant, has the best effectiveness.
