•B–Ti nanoenergetic coating was assembled via electrophoretic deposition.•Combustion test indicates quick energy releasing happened to B–Ti coating.•Ignition of Cu bridge assembled with B–Ti coating is exciting for ignitor application.
B–Ti nanoenergetic coating has received great attention on its high theoretical heat of reaction up to 5525 J g−1, which have great potential in enhancing the energy output of various function devices, including the micro-igniter device. In this work, B–Ti nanoenergetic coating was successfully fabricated via electrophoretic co-assembling of boron nanoparticles and titanium nanoparticles in a mixed solvent of ethanol–acetylacetone (1:1 in volume) containing 0.2 mM nitric acid. When electrophoretic deposition (EPD) were performed at higher concentration of B and Ti nanoparticles, more nitric acid is needed for sufficient surface charging. DSC curves show that the values of heat release in electrophoretic B–Ti nanoenergetic coating is 3329 J g−1. A violent and quick energy releasing of the B–Ti coating is successfully confirmed by the combustion test. With a significant enhancement in energy output by the electrophoretic B–Ti nanoenergetic coating, electro-thermal Cu bridge can be successfully ignited, exhibiting an exciting improvement in micro-ignitor application.
