New boron nitride polymer works well in capacitors

Ars Technica : Capacitors are a desirable alternative to batteries for electrical energy storage for home use and to power vehicles because they are lighter, discharge faster, and are easily rechargeable. Polymers would be the preferred material for use in capacitors but they don’t work well at the high temperatures (around 300 °C) required. Now a team has developed a composite polymer that makes use of boron nitride, which forms single-atom-thick graphene-like sheets surrounded by benzocyclobutene. Across a range of currents and temperatures, the resulting material matched or surpassed the currently available polymeric dielectrics. It also did not suffer any degradation under extreme mechanical deformation.
