Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a surface treatment method and application of inorganic nanoparticles. Background technique [0002] Inorganic nanoparticles are particles whose characteristic dimensions are on the order of nanometers, and have small size effects, quantum size effects, and surface effects. Combining inorganic nanoparticles and polymers to form polymer / inorganic nanocomposites has become a very active research field and shows good development and application prospects. However, due to the small particle size, large specific surface area, and high surface energy of inorganic nanoparticles, it is easy to agglomerate with each other, and it is difficult to maximize the nano-effect. [0003] Regarding the dispersion methods of inorganic nanoparticles in polymer materials, there are mainly physical dispersion methods, chemical dispersion methods, and dispersant dispersion method...
