Ultrahigh energy storage capability of trilayered polyetherimide/poly(vinylidenefluoride-trifluoroethylene-chlorofluoroethylene) with low loading of boron nitride nanosheets

We developed a trilayer film with linear PEI as outer layers and P(VDF-TrFE-CFE) composite as middle layer. Trilayer architecture contributes to the redistribution of local field, thereby greatly improving breakdown strength and energy density.
