Dispersion of Cs0.33WO3 particles for preparing its coatings with higher near infrared shielding properties

Influences of ball-milling and dispersant on the dispersion and stability of Cs0.33WO3 particles were investigated. Polyvinyl alcohol and titanate coupling agent have better effects on the dispersion of Cs0.33WO3 colloidal solution than poly-carboxylic salt dispersant. Excellent dispersion stability of Cs0.33WO3 particles could be achieved by adding titanate coupling agent after ball-milling at pH = 7 and the as-prepared Cs0.33WO3 coatings from the colloidal Cs0.33WO3 dispersion exhibited best visible light transmittance and near-infrared shielding properties.
