Abstract

Powder energetic materials are highly sensitive to electrostatic discharge (ESD) ignition. This study shows that small concentrations of carbon nanotubes (CNT) added to the highly reactive mixture of aluminum and copper oxide (Al+CuO) significantly reduces ESD ignition sensitivity. CNT act as a conduit for electric energy, bypassing energy buildup and desensitizing the mixture to ESD ignition. The lowest CNT concentration needed to desensitize ignition is 3.8vol.% corresponding to percolation corresponding to an electrical conductivity of 0.04S/cm. Conversely, added CNT increased Al+CuO thermal ignition sensitivity to a hot wire igniter.
