Boron Nitride Nanosheets: High Energy Density Polymer Dielectrics Interlayered by Assembled Boron Nitride Nanosheets (Adv. Energy Mater. 36/2019)

In article number 1901826, Xingyi Huang, Qi Li and co-workers develop novel composite films with a nanosized interlayer of assembled boron nitride nanosheets (BNNSs) that is aligned along the in-plane direction, representing a new paradigm for high performance dielectric materials. This compact interlayer of assembled BNNSs can largely block the propagation of electrical treeing, giving rise to improved dielectric energy storage performance.
