Recent progress on core-shell structured BaTiO3@polymer/fluorinated polymers nanocomposites for high energy storage: Synthesis, dielectric properties and applications

Abstract

This review aims at updating various studies to design BaTiO 3 @polymer/Fluoropolymer nanocomposites, to study their properties and performances and to supply their applications. Dielectric nanocomposite materials with high energy density exhibit promising performances for energy storage applications.Major efforts have been performed to combine the efficient properties and high dielectric constant of ceramics with the flexibility and easy processing of polymers.Actually, the dielectric properties of the nanocomposite are influenced by the dielectric features of both ceramic and polymer. Thus, the choice of the two components become crucial in turning the desired properties. Another important factor is the modification strategy to get such nanocomposites, where the major routes are the "grafting from", "grafting onto" and melt process while most fluoropolymers studied are polyvinylidene fluoride (PVDF), VDF containing-copolymers and terpolymers and poly(acrylates)bearing fluoroalkyl side groups. Additionally, fluorinated silanes have also been involved in sol-gel chemistry to decorate BaTiO 3 surface, as well as tetrafluorophthalic acid or fluorinated dopamine did. This review also summaries the current state of high energy density nanocomposites based on BaTiO 3 as a ceramic nanofiller and fluoropolymer as matrix.

Improved Energy Storage Performance of All-Organic Composite Dielectric via Constructing Sandwich Structure

“…However, the required properties for capacitor dielectrics, such as high energy storage density, high breakdown strength, and low dielectric losses, are often difficult to obtain in a polymer material at the same time. Therefore, for a long time, the optimization method of dielectric energy storage performance has been doping inorganic ceramic with high into polymers to prepare the inorganic-organic composite dielectric, and some achievements have been made [ 2 , 6 , 7 , 8 , 9 , 10 , 11 ]. However, due to the huge gap in dielectric properties and electrical conductivity between inorganic ceramics and polymers, electric field distortions are easily formed at the inorganic-organic interface, which may lead to deterioration of breakdown performance [ 12 , 13 ].…”

Three-dimensionally ordered macroporous BaTiO3 framework-reinforced polymer composites with improved dielectric properties

“…Polymer dielectric composites are expected to integrate excellent flexibility and easy processing of polymer matrixes with fillers with high dielectric constants. Various types of fillers, such as linear dielectrics [4,5], paraelectrics [6,7], ferroelectrics [8,9], relaxor ferroelectrics [10], antiferroelectrics [11,12], giant dielectric constant fillers [13,14] and conductive fillers [15,16], have been introduced into polymers to tailor their dielectric properties. Their high dielectric constants usually result from two aspects.…”

Recent Advances in the Synthesis of Polymer-Grafted Low-K and High-K Nanoparticles for Dielectric and Electronic Applications

“…Several recent reviews have comprehensively covered the topic of polymer grafting of nanoparticles [ 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. For example, the review by Ameduri et al, [ 35 ] dealt primarily with grafting of polymers on high-K NPs (BaTiO 3 ) for use in the formulation of high energy storage fluorinated polymer nanocomposites. In the present review, we cover the synthesis of polymer-grafted high-K and low-K nanoparticles for the fabrication of nanocomposites for electronics and dielectric application.…”
