Abstract

The invention relates to an aluminum-doped zinc oxide (AZO) nano particle thermosensitive material coating, a preparation method and application thereof, which belong to the technical field of nano materials and application. The method comprises four steps of preparing functional AZO nano particles, preparing a paint, preparing the coating, and representing the thermosensitive coating. According to the aluminum-doped zinc oxide nano particle thermosensitive material coating, the preparation method and the application thereof provided by the invention, AZO nano particle powder is dispersed in aspecific organic polymer solvent, and the AZO nano particles are stably dispersed in a water-based or oily solution and are then compounded with a resin to prepare into an energy-saving environmentally-friendly multifunctional paint with optical and thermosensitive properties, so that the problem of the stability of the AZO nano particles used as a window coating material is successfully solved.When the doping mol amount of aluminum is 3 percent, the aluminum has the best carrier density, and the AZO nano particle thermosensitive material has a similar property when the particle diameter ranges from 10 to 150 nm, has high transmittance in a visible region, and can selectively obstruct and penetrate through an infrared light in an infrared light region along with the temperature change atthe same time.
