Al/MoO3 nano-thermite has attracted wide attention due to its high heat released and fast combustion speed. In this paper, clubbed MoO3 with homogenous morphology was prepared by hydrothermal method at pH=1, reaction temperature 180°C and reaction time 24 h. Then Al/MoO3 nanocomposite coatings were assembled by electrophoretic deposition. Moreover, themorphology, structure, output of heat and combustion properties of the prepared samples were analyzed comprehensively. The results show that when the voltage is 200 V, the electrophoresis time is 10 min, the concentration of polyethyleneimine （PEI） is 1% and the ratio of two components is 2.13, the heat released of Al/MoO3 thermite reaches 3555 J/g, and the combustionphenomenon is violent. It is indicated that the micro-morphology and reaction ratio between Al and MoO3 have significant effect on the reaction performance of the Al/MoO3 thermite.
