Novel Ferroelectric Hybrid Poly(vinylidene fluoride)/Graphene Oxide Nanocomposite for Photosensor Applications
JOURNAL OF NANOELECTRONICS AND OPTOELECTRONICS(2016)
摘要
The graphene oxide (GO) nanosheets doped poly(vinylidene fluoride) (PVDF) nanocomposites were successfully fabricated using the solution blending. The structural properties of the PVDF/GO nanocomposites were investigated using the field emission scanning electron microscopy (FESEM) and transmission electron microscopy (SEM) techniques. The surface morphology properties of the PVDF/GO nanocomposites were changed with GO contents. The dielectric properties such as AC conductivity, real and imaginary permittivity as a function of frequency of PVDF/GO nanocomposites were determined. The prepared PVDF/GO nanocomposites exhibited a ferroelectric behavior. Finally, the applicability of as fabricated PVDF/GO nanocomposites for the rectifying was tested, too. The obtained results indicate that the PVDF/GO nanocomposites can be promising materials for heterojunction diodes.
