Some experts used sodium tungstate and cesium sulfate as raw materials to prepare the transparent aqueous phase dispersion of cesium tungsten bronze nanoparticles by hydrothermal method. Wherein, the preparation process conditions are: sodium tungstate concentration is 0.3mol/L, cesium/tungsten molar ratio is 0.3: 1, water/glycol volume ratio is 60:15, stirring time of precursor liquid is 1 h, hydrothermal pH value is 2, the hydrothermal heating rate is 2 °C/min, the hydrothermal temperature is 230 °C, and the hydrothermal time is 20 h. Then, the prepared dispersion with good optical properties and an aqueous resin can be blended to obtain cesium tungsten bronze heat insulation coating. And then the coating is coated on a glass substrate for building energy efficiency.
