Abstract

Abstract: In this study, nano‐Al/Fe2 O3 bilayer was successfully formed via aqueous electrophoretic deposition (EPD) route for the first time. For this formation, the first layer of nano‐Fe2 O3 was prepared by EPD using the bi‐additive of 0.015 mM HCl+10 mg L −1 PEI, and then the second layer of nano‐Al was immediately prepared by EPD using 5 mg L −1 PEI as additive. The electrophoretic nano‐Al/Fe2 O3 bilayer had high heat release of ∼2800 J g −1 and exhibited good combustion performance. In comparison with the previous work realized by using organic‐solvent‐EPD, we believe this study can pave a new way for preparing the bilayers of nanothermites or metallic reactive materials by more cost‐effective and environment‐friendly aqueous EPD route.
