Development of Electrically Controlled Energetic Materials (ECEM)

U.S. Army ARDEC has been examining a novel pyroelectric-type material developed by Digital Solid State Propulsion, LLC for its unique combustion properties and insensitivity. This unique ECEM is formed using an ionic liquid oxidizer and polymer fuel, via sol-gel processes and is quite dense, making it very suitable for energetic applications in both the civilian and military fields. This ECEM is completely insensitive to the application of impact, flame, friction, and shock threats. Once a power of the required voltage is applied, the baseline ECEM rapidly initiates combustion with H 2 O, CO 2 , and N 2 formed as the only major gas phase products produced. Initial testing of ECEM in perforated pipes appears promising as indicated by uniform ignition along the entire length of the test assembly.
