Researchers at INL havedeveloped methods for reducing the sensitivity of a non-high explosive materialto electrostatic discharge without appreciably impacting the material’sresponse to other initiation methods. This is achieved by adding small amounts(1-4 volume %) of graphene nanoplatelets or carbon nanotubes to increase theconductivity of a powdered composite energetic material. The addition of carbonincreases the powder’s conductivity by 10 orders of magnitude. When a currentis applied, it passes through the added carbon and does not heat the powder.Because the carbon constitutes a very small fraction of the total volume, thematerial remains fully responsive to normal ignition methods.
LICENSINGOPPORTUNITY: IdahoNational Laboratory (INL) and its M&O Contractor Battelle Energy Alliance,LLC (BEA) are currently looking for commercialization partner(s) interested inentering into a license agreement for the purpose of commercializing thetechnology described below. INTELLECTUALPROPERTY STATUS: US Patent No. 9,481,614, “Energetic Materials andMethods of Tailoring electrostatic Discharge Sensitivity of Energetic Materials,”issued on 11-1-16, BEA Docket No. BA-793. DEVELOPMENTSTATUS: This technology has been tested and validated at thebench scale. Additional development will be required to demonstrate a pilotscale process. BEA may be in a position to support additional research anddevelopment of this technology under a mutually acceptable Cooperative Research& Development Agreement (CRADA), Strategic Partnership Projects (SPP)agreement, or a similar agreement, all of which are subject to approval by DOE.
