Influence of Solution pH on Stability of Fumed Silica–Polyacrylic Acid Systems
The influence of polyacrlic acid (PAA) adsorption on fumed silica (SiO2) surface on suspension stability has been studied. Сhanges in the suspension stability were monitored using a Turbiscan LabExpert with a TLAb Cooler cooling module at 25oC. PAA is an anionic polymer containing carboxyl groups; t...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The influence of polyacrlic acid (PAA) adsorption on fumed silica (SiO2) surface on suspension stability has been studied. Сhanges in the suspension stability were monitored using a Turbiscan LabExpert with a TLAb Cooler cooling module at 25oC. PAA is an anionic polymer containing carboxyl groups; therefore all the measurements were carried out at different pH 3, 6 and 9. Analysis of obtained transmission and backscattering curves and Turbiscan Stability Indexes (TSI) allowed determination of the most probable mechanism of the system stability. |
