Polyacrylate polymer-vanadium dioxide microcapsule as well as preparation method and application thereof

The invention provides a polyacrylate polymer-vanadium dioxide microcapsule as well as a preparation method and application thereof, and belongs to the field of composite materials. According to the polyacrylate polymer and vanadium dioxide microcapsule provided by the invention, the particle size of the microcapsule is 20 to 100 nm. In the preparation process of the polyacrylate polymer and vanadium dioxide microcapsule, the reaction conditions are relatively mild, the preparation method is environment-friendly and safe, the operation is simple, the sample yield is high, the raw materials are cheap and easy to obtain, and large-scale production can be realized. And the microcapsule prepared by the invention is narrow in particle size distribution range and small in size, and can effectively reduce light refraction, thereby improving the optical performance of the microcapsule. The microcapsule material disclosed by the invention is used as an effective component of a heat-insulating coating to construct a co
