Abstract: The invention relates to nano fluorine-aluminum high energy release fuel and a preparation method thereof and aims to solve the problem that existing preparation method of fluorine-aluminum compoundsare more applicable to micro aluminum powder, a fluorine-containing shell on the surface of the micro aluminum powder is about 100 nm thick, for nano aluminum powder, the fluorine-containing shell of100 nm is too heavy and affects the performance of the nano aluminum powder. The nano fluorine-aluminum high energy release fuel consists of a nano aluminum core with an oxidation film removed and a shell. The method comprises the steps as follows: 1, mixing an HF solution and a solvent to obtain a mixed solution; 2, adding nano aluminum powder to the mixed solution, and stirring the mixture at normal temperature to obtain a mixed solution containing aluminum powder; 3, adding a perfluorocarboxylic acid solution to the mixed solution containing aluminum powder, and performing stirring at normal temperature to obtain a crude product; 4, washing the crude product with absolute ethyl alcohol and performing filtration under reduced pressure to obtain the nano fluorine-aluminum high energy release fuel. The method is used for preparing the nano fluorine-aluminum high energy release fuel.
