Polymer-based materials for achieving high energy density film capacitors

Chemically bonding BaTiO3 nanoparticles in highly filled polymer nanocomposites for greatly enhanced dielectric properties

“…Polymer-based high-dielectric-constant (high-k) materials have been explored for the extensive applications in modern electronic devices such as capacitors, actuators, sensors, and electromagnetic interference shielding due to their advantages of good processability, mechanical flexibility, light weight, low cost, and high breakdown strength [1][2][3][4][5][6][7]. Generally, it is challenging to use neat polymers to satisfy these needs because of their intrinsically low dielectric constant [8][9][10][11][12].…”

Rational Design of Soluble Polyaramid for High‐Efficiency Energy Storage Dielectric Materials at Elevated Temperatures

“…As film capacitors, polymer dielectric materials are widely used in advanced electronic devices and power systems. [ 1–7 ] With the development of modern technology, the miniature, light weight, and wearable electronic devices present a major development trend in electronic devices. Compared to ceramic materials, their counterparts, polymer dielectric materials have relatively low cost, high energy density, low dielectric loss, high breakdown strength, and good stability.…”

Interface modulation in multi-layered BaTiO3 nanofibers/PVDF using the PVP linker layer as an adhesive for high energy density capacitor applications

“…Furthermore, easily processable characteristics make PVDF attractive to be used as a polymer matrix. 12,[14][15][16][17] Recently, multi-layered polymer nanocomposite-based capacitors have been found to provide better dielectric performance than traditional single-layered nanocomposites as the interfaces between nanofillers and polymers as well as among different layers of the films help in increasing the polarization and simultaneously act as a barrier to block the path of electrical stress across the film, thereby increasing the breakdown strength and hence energy density. The literature suggests that researchers have explored different approaches to improve dielectric performance in a multi-layered capacitor.…”
