Effect of Nanoplatelet Size on the Colloidal Stability of Coupled Nanocomposite of TiO2 and Zirconium Phosphate Nanoplatelets

Effect of Nanoplatelet Size on the Colloidal Stability of Coupled Nanocomposite of TiO2 and Zirconium Phosphate Nanoplatelets

The aggregation and sedimentation of nanoparticles affect the dispersion stability and application of nanosuspension. TiO<sub>2</sub> nanoparticles were coupled on zirconium phosphate (ZrP) disks with different diameters to study the effect of ZrP size on the dispersion stability of nano...
