Fabrication and characterization of free-standing, flexible and translucent BaTiO3-P(VDF-CTFE) nanocomposite films

High Energy Storage Density of Sandwich-Structured Na0.5Bi0.5TiO3/PVDF Nanocomposites Enhanced by Optimizing the Dimensions of Fillers

“…In the high frequency range, it increases with increasing frequency. This characteristic behavior is closely related to the motion of segments of polymer chain . The behavior also can be linked to different processes/mechanisms, such as conductivity, relaxation associated whole polymer chain motion, and imperfection of crystallization (i.e., interfacial layer between the crystal and amorphous).…”

Enhanced breakdown strength and suppressed dielectric loss of polymer nanocomposites with BaTiO3fillers modified by fluoropolymer

“…In addition, the increased content of the BT nanoparticles in the nanocomposite lm can induce interfacial polarization and enhance the Maxwell-Wagner-Silars effect. 36,37 As the frequency increases, the dielectric constant of the nanocomposite lm gradually decreases and maintains relatively high stability at low frequency (10 2 to 10 5 Hz). In contrast, the dielectric constant of the nanocomposite lm shows a signicant decrease in the high-frequency range (10 5 to 10 7 Hz).…”

Preparation and characterization of flexible, free‐standing, and easy‐fabricating BaTiO3‐P(VDF‐CTFE) dielectric nanocomposite

“…Currently, the most widely studied polymer‐based dielectric composites are so‐called 0‐3 composites, in which a matrix with a high E b is filled with either conductive nanoparticles or dielectric nanoparticles with a large ε r . Among the polymers used as the matrix material in the 0‐3 composites, polar polymers, such as PVDF‐ and PVDF‐based copolymers, attracted the most of attentions, since they exhibit a higher ε r (~10) than nonpolar polymers (<5) . Regarding the fillers, ceramics with high ε r such as BaTiO 3 (BT), (Ba,Sr)TiO 3 (BST), Pb(Zr,Ti)O 3 (PZT), CaCu 3 Ti 4 O 12 (CCTO), etc., have been used.…”

“…It is known that the properties of a 0‐3 composite are significantly affected by the uniformity of its microstructure and the compatibility between its constituents . To develop the composites with a uniform microstructure, different approaches have been investigated, such as hot‐pressing and spin‐coating . Due to the poor wettability between polymer and ceramics, these approaches cannot really improve the compatibility between the constituents of the composites.…”
