Flexible, transparent and high dielectric constant fluoropolymer-based nanocomposites with fluorides-constructed interfacial structure

Abstract

Flexible transparent dielectric materials have drawn ever increasing research interests owing to their essential functions and potentially expansive applications in new generation electronics. In this work, a well-designed fluorides-constructed interfacial structure between poly(vinylidene fluoride-co-hexafluoro-propylene) P(VDF-HFP) and ultra-small SiO2 nanoparticles was formed for manipulating the crystallization of the semicrystalline polymer. With induced more polar phases, ameliorated matrix/filler interfaces and diminished crystallite sizes, the resulting fluoropolymer-based nanocomposites exhibit high dielectric constant, low dielectric loss of 27.1, 0.03 at 1 kHz, respectively, as well as enhanced mechanical strength (986.2 MPa in Young′s modulus), toughness (208.2% in elongation at break) and light transmittance (88.5% at 760 nm). This strategy is believed to open a new path for developing high-performance flexible transparent dielectrics.
