Description

technical field [0001] The invention relates to a preparation method of a nano zirconia powder dispersant and a nano zirconia powder dispersant prepared by the method. Background technique [0002] Inorganic nanopowders have special properties in terms of magnetism, catalysis, light absorption, electrical conductivity, hardness and melting point, and have attracted great attention. As an important aspect of the application of inorganic nanopowders, inorganic nanopowder filled modified polymer blends have become a hot spot in the field of polymer material theory and application research in recent years. In the preparation of inorganic nanocomposites, due to the small particle size, large specific surface area and total surface energy of inorganic nanopowders, nanopowders are easily agglomerated to form large particles, making it difficult to obtain real nanocomposites. Therefore, it is necessary to modify the surface of the inorganic nanopowder to improve its dispersibility ...
