Preparation of core-shell structure KClO4@Al/CuO Nanoenergetic material and enhancement of thermal behavior

Abstract In this paper, a solvent/non-solvent synthetic approach has been utilized in preparing a new nanoenergetic material KClO4@Al/CuO by coating Al/CuO nanocomposites particles with a layer of nanoscale oxidizer KClO4. The coating process and mechanism are discussed. The composites of Al/CuO are...
