The sensitivity of nanothermites to electrostatic discharge (ESD) has been noted by many authors. In the present work, nanothermites have been prepared using aluminium fuels with oxide (O-Al), palmitic acid (L-Al) and Viton (V-Al) passivation and CuO, Fe2O3 and MoO3 oxidants, as well as binary oxidant mixtures. Fuel- and oxidant-based ESD sensitivity trends of O-Al ≈ L-Al >> V-Al and MoO3 >> CuO ≈ Fe2O3 were observed with binary oxidants affording intermediate sensitivities. In the majority of cases, with the exception of high proportions of MoO3 oxidant, nanothermites containing V-Al fuel were the least sensitive to ESD at > 0.156 J. Resistivity measurements have been made for the fuels and oxidants and follow the trends V-Al >> O-Al ≈ L-Al and MoO3 >> Fe2O3 > CuO. V-Al resistivity of ca. 1011 Ω·cm exceeds that of the oxidants studied. An ESD sensitivity trend, based on a reduced proportion of spark current carried by the aluminium fuel, is proposed and was consistent with the observed ESD and resistivity data.
