| 摘要 |
The present invention relates to a method for preparing so-called modified hexagonal boron nitride particles with metal nanoparticles attached thereto by stable bonds, comprising the following steps: a) providing a reaction mixture comprising either the metal nanoparticles directly, or a water soluble precursor salt of the metal nanoparticles, urea, hexagonal BN particles, water, and an acid, so as to reduce the pH of the reaction mixture, b) then, stirring and heating the reaction mixture, in such a way as to attach the metal nanoparticles or nanoparticles containing the metal element used in order to obtain the desired metal nanoparticles after treatment, to the BN particles, c) washing the modified boron nitride particles closed in this way, and the modified BN particles which can be obtained according to such a method. |
