Wrinkling in graphene sheets and graphene oxide papers

Carbon, 2014
The formation mechanisms of wrinkles in single layer graphene sheets and graphene oxide (GO) papers, as well as their effects on the corresponding Young’s moduli have been studied based on the molecular dynamics simulations. Wrinkling occurs in GO papers in the form of undulation as a consequence of the interactions between the adjacent individual GO ...

Resistivity comparison of graphene oxide and graphene oxide-silver nanocomposite paper

NAECON 2014 - IEEE National Aerospace and Electronics Conference, 2014
Most carbon nanomaterials are touted for their unusual conductive or semiconductive properties. In this paper, we compare the many-layered graphene oxide (GO) and GO-silver nanocomposite “papers” to elucidate their unusual resistive properties. We have observed significant nonlinearities in resistivity, its dependence on temperature, and current ...

An economic route to mass production of graphene oxide solution for preparing graphene oxide papers

Materials Science and Engineering: B, 2015
Abstract Graphene oxide paper (GOP) is a composite material fabricated from graphene oxide (GO) solution. In addition, it can be a novel and potential material for application on the separation of water vapor from gaseous steam or larger alkali ions from aqueous solution. GOP could be used as electricity and thermal storage materials. The preparation

Fabrication and Plastic Deformation of Graphene Oxide Paper

ECS Meeting Abstracts, 2020
Graphene oxide (GO) derives from graphite through oxidation, with subsequent dispersion and exfoliation in suitable solvents [1]. GO contains various oxygen-containing functional groups, mainly including hydroxyl, carboxyl, carbonyl and epoxy groups [2].

Hierarchical Structure and Properties of Graphene Oxide Papers

Journal of Applied Mechanics, 2013
The mechanical properties of graphene oxide papers have attracted significant attention in recent years due to their high stiffness and tough behavior. While the structural feature most commonly characterized is the nanosheet spacing, there is a hierarchical structure, which is likely responsible for the impressive mechanical properties. In this paper,

Temperature-dependent electrical property transition of graphene oxide paper

Nanotechnology, 2012
Reduction of graphene oxide is primarily important because different reduction methods may result in graphene with totally different properties. For systematically exploring the reduction of graphene oxide, studies of the temperature-dependent electrical properties of graphene oxide (GO) are urgently required.

Advanced graphene oxide-based paper sensor for colorimetric detection of miRNA

Microchimica Acta, 2021
MicroRNAs (miRNAs), found in blood and body fluids, have emerged as potential non-invasive biomarkers for disease and injury. miRNAs are quantitatively evaluated using typical RNA analysis methods such as the quantitative reverse transcription polymerase chain reaction, microarrays, and Northern blot, all of which require complex procedures and ...

Reduced graphene oxide paper as bimorphic electrical actuators

Materials Letters, 2017
Abstract Reduced graphene oxide (rGO) papers prepared by simple self-assembly process were used as electrode material for the fabrication of bimorphic electrical actuators. Initially, the structural studies of the rGO paper confirmed the formation of graphitic structure. The ionic gel electrolyte was prepared separately and used to couple the two rGO

High performance supercapacitor electrode based on graphene paper via flame-induced reduction of graphene oxide paper

Journal of Power Sources, 2013
Abstract Reduced graphene oxide (r-GO) paper is easily synthesized by a flame-induced reduction of graphene oxide (GO) paper under ambient conditions. The X-ray diffraction and X-ray photoelectron spectroscope results confirm the effectivity of the flame-induced reduction.
