Abstract
As the basis of the modern electronics industry, electronic functional materials provide powerful support for the development of science and technology. Biaxially oriented polypropylene (BOPP) dielectric films are widely used in capacitors for excellent dielectric advantages. In this paper, a topological-structured multilayer sandwich dielectric film was designed. BOPP was used as the outer layer, the blend of chlorinated polypropylene/polyvinylidene fluoride (CPP/PVDF) as the middle layer, and two-dimensional boron nitride nanosheets (BNNS) were added to the CPP/PVDF blend to enhance its breakdown strength. The sandwich-structured films had the highest discharged energy density of 5.17 J cm-3at 3 vol% addition of BNNS in the middle layer, and the charge-discharge efficiency maintained at a high level of 82.1%. The dielectric and energy storage properties of BOPP sandwich films were effectively improved by the introduction of large aspect ratio fillers.
期刊介绍：
The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
