Dispersion of TiO2 Nanoparticles in Aqueous Solution

Abstract:

Article Preview

Stable TiO2 aqueous dispersion with an averaged secondary particle size of about 10 nm was achieved by using commercially available dispersant Di-7N. The stability of the dispersion was measured by Zeta-potential test. And the results showed that the optimal mass fraction of Di-7N was 12 wt%. The adsorption mechanism examined by FTIR analysis indicates that the carboxylate groups in Di-7N is absorbed on the surface of nano-TiO2 particles and the adsorbed structure is proposed to be bidentate chelating.
