In this work, leveraging the principle of electrical/thermal synergistic enhancement, a series of facile dual-layered polymer-based nanocomposites are fabricated, with pure polyvinylidene fluoride (PVDF) as the top layer and boron nitride nanosheet (BNNS)/polyetherimide (PEI) as the bottom layer.
In this paper, we report the mechanism by which P&F produces relaxor-like ferroelectric behaviour in PVDF, and use this knowledge to optimise its energy storage properties.
Herein, we proposed a strategy that utilized (00 l)-oriented barium titanate (BT) single-crystal platelets to fabricate trilayered nanocomposite dielectrics for energy storage applications.
This study not only advances the development in high-performance dielectric energy storage PVDF-based nanocomposites but also opens new avenues for future research, focusing on the synergistic enhancement of dielectric properties with minimal filler loading.

Low-cost, free-standing, relaxor-like ferroelectric PVDF films prepared using a facile press-fold approach. >98% fraction of polar β -phase with nano-crystallite size of ~3 nm.
PVDF exhibits a high relative permittivity εr of ~10–12 (1 kHz) and high field-induced polarization Pin (~0.10 C/m 2) at high applied electric fields (~200 kV/mm) due to the non-polar α phase to polar δ phase transition at 170 kV/mm, followed by the β phase transition at 500 kV/mm [10, 11].
Hot-pressed film: 4.0 g of PVDF powder was weighed using an analytical balance (OHAUS Explorer, USA) and placed between two aluminium sheets.
