Abstract: |
The surface modification of nano-sized TiO2/ZnO power and the effect factors were studied, the optimal modifying agent and condition were found. The prepared samples were characterized by FTIR, TEM and TG techniques. The results showed sodium laurate was the best modifying agent and optimal condition was 15% dosage, pH 5 and 1.5 h, its lipophilic degree was 86.3 %. According to the spectra of FTIR and TG, it was inferred that the sodium laurate was bound on the surface of nano-sized TiO2/ZnO and the mass fraction of the sodium laurate on the surface of nanosized TiO2/ZnO was about 14 %. The TEM and dispersibility experiment showed nanosized TiO2/ZnO modified with sodium laurate could be better dispersed in toluene.
