Abstract In this work, a silver nanoparticle‐boron nitride nanoplate (Ag‐BN) hybrid filler was prepared using an effective microwave‐heating method in only 2 min and utilized as functional for polyvinylidene fluoride (PVDF)‐based composite. The successful deposition of Ag nanoparticles on BN nanoplates, forming the Ag‐BN filler, confirmed through series microstructural characterizations FTIR, WAXD, UV–Vis, SEM, TEM, EDS mapping. Furthermore, it found that incorporation into PVDF effectively enhanced crystallization behaviors, dielectric properties, thermal conductivities resultant Ag‐BN/PVDF composites. For example, nonisothermal‐crystallization‐peak temperatures, degrees, contents polar β ‐ γ ‐form crystallines PVDF, constants, loss tangents, pure Ag‐BN1(10 wt.%)/PVDF composite are 136.2 143.7°C, 41.37% 53.41%, 26.0% 72.6%, 8.2 15.0, 0.023 0.024, 0.12 0.31 W/m·K, respectively. Highlights obtained from rapid method. Novel composites were solution‐blending can induce crystalline PVDF. have property compared to conductivity

Flexible magnetoelectric composite devices have exceptional features and potential in peculiar scenes. However, maintaining the response under extreme bending conditions remains a challenge. Polyvinylidene fluoride-based polymers, possessing favorable piezoelectric properties high flexibility, provide viable solution for composites. This work constructed multiferroic core-shell nanoparticle-embedded flexible membranes achieved retainable (ME) coupling coefficient curved materials. A maximum ME of 74 mV cm−1 Oe−1 was obtained, far higher than 0–3 nanocomposites reported thus far. The can be maintained above 40 when angle is less 90° expresses sensitivity within Hdc range 100–2400 Oe. Based on crystal structure analysis phase-field simulation, synergy effects accounting nanoparticles, copolymer matrix, magnetic cores contribute to promoted provides feasible pathway next-generation wearable portable fields.
