Enhanced dielectric properties of PVDF-based composite film with BaTiO₃@SrTiO₃nanoparticles

Abstract

A new ceramic/polymer composite based on BaTiO3@SrTiO3 (BT@ST) nanoparticles and Polyvinylidene fluoride (PVDF) had been prepared. It was proved that the BaTiO3@SrTiO3 nanoparticles were dispersed in the polymer matrix by...

“…Hal lainnya juga terlihat dari laporan Maity et al dan Liu et al pada komposit PVDF/BST dengan kenaikan komposisi filler BST menyebabkan kenaikan konstanta dielektrik [69][70] . Dari ketiga variasi komposit PVDF/BaTiO3, PVDF/BZT dan PVDF/BST dapat disimpulkan bahwa filler bebasis material oxide dari komposit PVDF sangat berpengaruh terhadap kenaikan nilai kontanta dielektrik dibandingkan dengan nilai karakteristik dari PVDF sendiri dan juga didapatkan bahwa konstanta dielektrik komposit PVDF/BaTiO3 tidak lebih besar dari konstanta dielektrik BaTiO3 [71][72][73][74][75][76][77][78] .…”

Achieving Enhanced Interfacial Interaction and High Dielectric Properties in PVDF Composite Film Containing Polyaniline-Derived N-Doped Carbon

“…1−3 To obtain low-cost, easy-to-process, and highperformance dielectric materials, poly(vinylidene fluoride) (PVDF) is often combined with high dielectric constant fillers to obtain composite materials with superior dielectric properties. 4,5 The fillers of PVDF dielectric composites mainly involve the ceramics, conductors, and organic compounds. Most of the ceramic fillers have high dielectric constant, such as barium titanate (BT) and barium strontium titanate (BST).…”

“…With the rapid development of electrical and electronic products to the direction of high integration, large scale, portability, and high performance, traditional dielectric materials can no longer meet the requirements of the modern industry. − To obtain low-cost, easy-to-process, and high-performance dielectric materials, poly­(vinylidene fluoride) (PVDF) is often combined with high dielectric constant fillers to obtain composite materials with superior dielectric properties. , The fillers of PVDF dielectric composites mainly involve the ceramics, conductors, and organic compounds. Most of the ceramic fillers have high dielectric constant, such as barium titanate (BT) and barium strontium titanate (BST). , The addition of ceramic particles can greatly improve the dielectric constant of the composite system, but the incompatibility of ceramic fillers with the matrix and the defects generated in the sintering process will affect the dispersion of fillers in the matrix and cause great dielectric loss.…”

Molecular engineering of a polyimide copolymer enables excellent dielectric and energy storage performance

“…Due to their virtues of being light weight, easy processability and flexibility, high permittivity polymer dielectric materials have drawn considerable attention for potential applications in advanced dielectric capacitors, integrated circuit dielectrics and electromagnetic interface shielding. 1–6 Unfortunately, the application of polymer dielectric materials in the field of compact-size electronic devices and severe environments is restricted by their inferior energy densities and poor operating temperatures. 1,6,7 For instance, the energy density of commercial biaxially-oriented polypropylene (BOPP) is usually below 2.0 J cm −3 because of its low permittivity.…”
