Abstract
A heat-insulating energy-saving film includes a substrate, an infrared blocking layer and an antifouling protective layer. The infrared blocking layer is disposed on a surface of the substrate and the antifouling protective layer is disposed on the infrared blocking layer, in which the infrared blocking layer has a plurality of composite tungsten oxide particles uniformly distributed therein. The composite tungsten oxide particles of the infrared blocking layer are each doped with specific metal and non-metal elements, such that the infrared cut rate of the infrared blocking layer is capable of reaching 99%.
