▎ 摘　　要

A novel and facile method, to synthesize high-quality fluoro-functionalized graphene oxide (F-GO) and polyvinylidene fluoride (PVDF) composite (F-GO/PVDF) films prepared by solution blending of F-GO and PVDF in solution was proposed. The fabricated F-GO/PVDF nanocomposites with different mass fractions exhibited high dielectric constant and low dielectric loss. Meanwhile, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy and raman spectroscopy verified the functional groups in the F-GO. The microstructure analysis using X-ray diffraction and field-emission scanning electronmicroscopy were performed to investigate the morphology of F-GO and F-GO/PVDF composite films. The thermal, hydrophilic and electrical characterization properties of F-GO/PVDF composites were investigated by thermal gravimetric analysis, contact angle, and dielectric constant. These results indicate their potential applications for dielectric devices storage devices.
