Abstract
The invention provides a high-stability boron-loaded tin oxide binary composite energetic material and a preparation method thereof, the method takes elemental boron as a carrier, and the method adopts an atomic layer deposition method to load a tin oxide film on the surface of the elemental boron to prepare the boron-loaded tin oxide binary composite energetic material. A deposition period of the atomic layer deposition method comprises the following steps: firstly, depositing a tin-containing precursor on the surface of elemental boron, and then carrying out chemical reaction on the deposited tin-containing precursor and an oxidizing agent to generate a tin oxide thin film. The tin-containing precursor is tetra (dimethylamino) tin; the oxidizing agent is water, oxygen or ozone. The reaction temperature of the atomic layer deposition method is 150 DEG C. And the thickness of the tin oxide thin film is 0.1-10 nm. And the content of the tin oxide thin film is 1.0 wt%-7.0 wt%. The B-coated SnO2 binary composite energetic material prepared by the invention has higher initial oxidation reaction temperature and longer laser ignition delay time, so that the stability of the energetic material is remarkably improved.
