Transparent aqueous dispersion of cesium tungsten bronze has good optical properties - a visible light transmittance of 75% at 500nm, and a near infrared light blocking rate of 90% at 1000nm. Wherein, cesium tungsten bronze nano particles that have a small particle size and uniform particle size distribution are uniformly dispersed in water with good stability.

According to the experts, transparent aqueous dispersion of cesium tungsten bronze can be prepared by hydrothermal method, which is often used to prepare transparent organic-inorganic composite thermal insulation coating. The prepared thermal insulation coating is the main development direction of energy-saving technology for building glass, so cesium tungsten bronze has also received widespread attention. It is reported that transparent aqueous dispersion of cesium tungsten bronze with high visible light transmittance and good near-infrared shielding performance can be prepared via simple production process, and the cost is relatively low.
