Absence of giant dielectric permittivity in graphene oxide materials

Graphene oxide (GO) is considered as a promising component for electronics because of its unique anisotropy, easy processing and sometimes claimed giant permittivity. The latter would arise from an



Dielectric properties of graphite‐based epoxy composites

Composite materials based on epoxy resin filled with various kinds of graphite particles: exfoliated graphite, natural graphite, and coarse, medium and fine artificial graphites have been prepared.

Electric-field dependence of the effective dielectric constant in graphene.

This work addresses the issue of the effective dielectric constant (ε) in N-layer graphene subjected to out-of-plane (E(ext)(⊥)) and in-plane(||) external electric fields and points to a promising way of understanding and controlling the screening properties of few- layer graphene through external electric Fields.

Exfoliated graphite (EG) refers to graphite that has a degree of separation of a substantial portion of the carbon layers in the graphite. Graphite nanoplatelet (GNP) is commonly prepared by

Facile synthesis of graphene sheets from fluorinated graphite

One of the problems with the chemical exfoliation of graphite to graphene via oxidation and reduction, is the excessive oxidation of graphite and incomplete reduction of graphene oxide, which

Graphene‐based composite materials with high dielectric permittivity via an in situ reduction method

Novel nanocomposites with graphene as conductive filler have been prepared through simple ultrasonic exfoliation of graphite oxide (GO) and subsequent in situ reduction approach. The graphene oxide

Ultra high permittivity and significantly enhanced electric field induced strain in PEDOT:PSS–RGO@PU intelligent shape-changing electro-active polymers

Large deformation of soft materials is harnessed to provide functions in the nascent field of soft machines. In this work, PEDOT:PSS noncovalent functionalized graphene–polyurethane dielectric

Dielectric properties and magnetoresistance behavior of polyaniline coated carbon fabrics

Carbon fabrics (CFs) coated with 5.0, 15.0 and 30.0 wt% polyaniline (PANI) (PANI–CFs) have been synthesized by soaking CFs in a 1.0 wt% PANI formic acid solution. The real permittivity (e′) of the
