Problems solved by technology

[0003] However, the transparent heat insulation performance of the heat insulation film made of ATO and ITO is not ideal, especially the reflection and absorption ability in the near infrared region is relatively poor.
In contrast, ATO has a better blocking effect on IR than ITO in the region of light waves less than 900 nanometers, but if the vis

Description

technical field [0001] The invention relates to a new heat-insulating and energy-saving material, in particular to a heat-insulating and energy-saving WO 3 Nanopowder, the WO 3 The powder is blue and has the functions of transparency, heat insulation and UV protection; in addition, the invention also relates to the heat insulation and energy saving WO 3 Preparation method of nanopowder. Background technique [0002] WO currently produced at home and abroad 3 Most of the powders are light green or light yellow powders, and the morphology features are all spherical or strip-shaped, and these powders do not have transparent heat insulation properties, only have certain transparency and UV protection functions or other optical properties. At present, nano-materials such as ATO and ITO are often used at home and abroad to prepare transparent heat-insulating glass or transparent heat-insulating film. [0003] However, the transparent heat insulation performance of the heat ins...
