| Abstract: | Dispersion and stabilization of nanoparticles in media is the critical problem for their synthesis and applications. Adsorption behavior of various polymers on the surface of SiO2 and ZnO nanoparticles was investigated. Effects of polymer concentration,pH value,ionic type and concentration on the stabilization of colloidal dispersion were discussed. The dispersion mechanism was suggested by changing the macromolecular type and dispersion conditions, |
