Abstract

The invention relates to a preparation method for a barium titanate / graphene composite nanometer material, and the method employs a wet chemical reaction process. The preparation steps comprise: taking 2-methoxyethanol as a solvent dissolving a titanium ion, utilizing ammonia water as a precipitating agent to precipitate titanium ion, adding an aqueous solution of graphene oxide, and fully mixing; utilizing a deionized water solution of barium acetate as a barium source, and taking a mixed solution of ethylenediamine and ethanolamine as a solvent; and finally utilizing a mineralization agent potassium hydroxide to promote crystallization, and performing hydro-thermal reaction to obtain the barium titanate / graphene nanometer powder. The preparation method is simple in process, easy to control, free of pollution and low in cost, and the prepared barium titanate / graphene composite nanometer material is high in purity and good in crystallinity.
