Abstract

Highlights

A bilayer dielectric film is prepared via coating boron nitride nanosheets (BNNSs) by solution casting on the surface of polyethylene terephthalate (PET) film.
The BNNS layer acts as the efficient barrier layer to suppress the charge injection, thereby making the surface-modified PET films exhibit excellent breakdown strength and electrostatic energy storage performance.
The surface coating methods are accessible and suitable for large-scale roll-to-roll process production of dielectric films.

一种具有优异击穿强度和储能密度的双层高温介质薄膜

在聚对苯二甲酸乙二醇酯(PET)薄膜表面采用溶液浇铸法制备了氮化硼纳米片(BNNSs)双层介质薄膜。BNNS层作为有效的阻挡层抑制电荷注入，从而使表面改性PET薄膜具有优异的击穿强度和静电储能性能。表面涂覆方法易于获得，适合大规模卷对卷工艺生产介质薄膜。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
