Reactive Materials with Reduced Electrostatic Discharge Sensitivity
Agency / Branch:
DOD / ARMY
Advanced reactive materials (RM) with reduced electrostatic discharge (ESD) sensitivity are needed by the Army. Nanoscale thermite compositions are of particular interest because of the fast reaction rates and high flame temperatures generated during reaction. Unfortunately, in many cases, the materials are so reactive that they are impractical to work with. One route to improving ESD insensitivity is to embed the nanoparticles in a polymeric matrix, which insulates the particles from accidental discharge. However, significant challenges exist with traditional polymeric nanocomposite processing, including achieving monodisperse, non-agglomerated particle suspensions. These challenges only increase with larger batch sizes, making production scale-up another significant challenge. Cornerstone Research Group Inc. (CRG) proposes to develop polymeric nanothermite composites using a novel, patented process called nanoinfusion. Nanoinfusion processing technology allows for in-situ formation of nanoparticles in a polymer matrix, producing polymer nanocomposites with monodisperse nanoparticle content. Nanoinfusion is not a liquid dispersion process, and there is no handling of loose nanoparticles. There is no route for particle agglomeration in this process, eliminating the most significant processing challenge associated with nanoparticle synthesis and mixing. Nanoinfusion is scaleable to meet large scale production needs, while safely and consistently achieving excellent nanoparticle dispersion and size uniformity.
