| Abstract: | In this paper,polyeletrolyte and other dispersants were used to prepare the nano-SiO_2 aqueous suspension.The dispersing hehavior and the surface chemical properties of the nano-SiO_2 in the water were studied based on the mechanisms of electrosteric stabilization and by means of Zeta-potential and particle size measurement.The influence of pH value,dispersant content on the suspension stability and the viscosity is discussed.The stable aqueous nano-SiO_2 suspension with high solid content were obtained under the optimum condition. |
