That is because the blending method is simple to operate. And the type, shape and size of the nanoparticles prepared by this method can be controlled. Also, this method is economical and easy to realize industrialization. Therefore, most researchers in China use the blending method to prepare water-based transparent heat-insulating glass coatings. Among them, as the composite materials prepared by the traditional mechanical blending method and melt blending method are difficult to achieve nano dispersion level, the nano particles are dispersed by ball milling or other high-efficiency methods in a liquid medium to obtain nano dispersed slurry, and then mixed with the polymer base. At present, the preparation methods of nanocomposite mainly include blending method, sol-gel method, intercalation method, in-situ dispersion polymerization method and radiation synthesis method.
