High-Temperature Dielectric Nanocomposite

A nanocomposite was developed that could be a superior high-temperature dielectric material for flexible electronics, energy storage, and electric devices. The nanocomposite combines one-dimensional polymer nanofibers and two-dimensional boron nitride nano-sheets. The nanofibers reinforce the self-assembling material while the white graphene nanosheets provide a thermally conductive network that allows it to withstand the heat that breaks down common dielectrics, the polarized insulators in batteries, and other devices that separate positive and negative electrodes.
