Cesium tungsten oxide such as nano particle size Cs0.33WO3 is made into dispersion before preparing into greenhouse heat insulation coating. As the properties of dispersion will affect the final energy-saving product - greenhouse heat insulation coating, the experts studied the zeta potential and absorbance of colloidal Cs0.33WO3 dispersion at different pH value.

And it was found that Zeta potential declined with too high or too low pH value, which is not conducive to decentralizing the particles. High zeta potential can keep Cs0.33WO3 particles surface a certain distance and decrease the molecular reaction, and as a result, a stable dispersion system could be formed. Obviously, the absorbance will decrease in strong acid and strong base, because electrostatic repulsion cannot afford to resist attraction, and the particles become easy to agglomerate and precipitate. In a word, to obtain cesium tungsten oxide with good dispersibility and stable dispersion system for preparing greenhouse heat insulation coating, it requires a proper pH value to get high zeta potential.
