All-organic PVDF-based composite films with high energy density and efficiency synergistically tailored by MMA-co-GMA copolymer and cyanoethylated cellulose

Abstract

All-organic polymer dielectric films have been widely used for different electrical devices in recent years. However, their development is impeded by the low Ue and large device volume. In the...

Crosslinking modification and hydrogen bonding synergy to achieve high breakdown strength and energy density of PMMA-co-GMA/PVDF dielectric composite films

“…Similar results about the hydrogen bond formation mechanisms have also been reported in some studies. 33–35 Therefore, the FTIR results suggest that PEA/MG–PVDF composite films can form multiple hydrogen bonding interactions.…”

Higher hydrogen fractions in dielectric polymers boost self-healing in electrical capacitors

“…[11][12][13] The goal of the researchers is to design highly reliable capacitors, that not only separate large coulombic charges on the counterplates but also prevent accidental discharges, and minimize the corruption of the electrodes and dielectric materials. [14][15][16] The adverse processes, such as dielectric breakdowns, can be prevented by improving the designs of the electrical capacitors and tuning the properties of the employed insulating polymeric films.…”

Cross-Linked Poly(vinylidene fluoride-hexafluoropropylene)-graft-poly(glycidyl methacrylate) Achieved Enhanced Dielectric Properties and Charge–Discharge Efficiency

“…37 Meanwhile, the hydrogen bonds were also manifested to serve as trapping sites for charge carriers to restrain the conduction loss and improve E b . 29 Sun et al 38 reported the deep trap effect of hydrogen bonding between PVDF/P(methyl methacrylate-coglycidyl methacrylate) P(MMA-co-GMA), which enhanced the dielectric breakdown strength and the charge−discharge efficiency by reducing the charge carrier motion.…”
