Zinc oxide is a typical N-type semiconductor. Due to the presence of interstitial zinc ions and oxygen vacancies in ZNO itself, its resistivity is high and its band-gap width is narrow, which limits its application range. Doping some substitute elements such as AL3+ in ZNO can reduce the resistivity of ZNO and improve its photoelectric performance. Aluminum Zinc oxide nanomaterials have excellent thermal insulation properties and good thermal conductivity.
The application of AZO aluminum zinc oxide nanoparticles in polyacrylic resin composite coatings can significantly improve the thermal insulation performance. First of all, AZO aluminum zinc oxide nanoparticles have low thermal conductivity, which can effectively block the heat transfer. Secondly, the AZO aluminum zinc oxide nanoparticles in the composite coating can efficiently reflect and absorb thermal radiation, and reduce the heat absorption of the surface. In addition, AZO aluminum zinc oxide nanoparticles also have UV resistance, oxidation resistance and weather resistance, which can protect the polyacrylic resin composite coating from external environmental damage. In addition, according to research, almost all film preparation methods (such as magnetron sputtering, sol-gel, vapor deposition, etc.) can be used to prepare AZO films.
