- *Abstract
-
Northwestern University scientists have developed an advanced nanocomposite material that improves upon currently available dielectrics. Capacitors and many other technologies are based on dielectric materials. However, to enable further advances in capacitor production a dielectric with high permittivity, high breakdown strength, low loss and fast response is needed. The Marks group invented just such a material, when they designed a nanocomposite that merges two types to dielectrics, a metal particle and a polymer. The resulting aluminum nanoparticle-polymer nanocomposite is simple to produce in addition to having a favorable energy storage profile. This novel dielectric material could become a disruptive technology contributing to medical, automobile and defense industries by enabling next-generation high energy density pulsed-power capacitors.
