Effect of Ethanol on the Stability of Pigment Colloidal Dispersion

摘要：

The effects of ethanol on the thickness and ionization of adsorbed polymer layer on pigment were investigated.The results showed that the thickness of adsorbed polymer layer decreased with the increase of the ethanol concentration,and the pigment particles aggregated when the concentration of ethanol was higher than 40％.The zeta potentials became more negative with the increase of the ethanol concentration,and changed reversely when the ethanol concentration was higher than 16％.The thickness and structure of adsorbed polymer layer on the particle determined the stability of pigment dispersion.
