Graphene oxide paper can be systematically modified with alkylamines in both solution- and vapor-phase, with the latter process being significantly slower. After removal of physisorbed amine, the increases in gallery spacing, physical thickness, and

The thermal stability and reduction kinetics of graphene oxide were studied by measuring the electrical resistivity of single-layer graphene films at various stages of reduction in high vacuum and by performing temperature programmed desorption (TPD)

The structure of graphite oxide has been studied by neutron diffraction and is found to be nano-crystalline, the diffraction pattern being a mixture of Bragg and diffuse scattering. Three strong Bragg peaks were found in the structure factor from whi

Thin layers of graphite oxide sheets were dispersed in dimethylformamide and dielectrophoretically assembled onto predefined and opposing metal electrodes. The dielectrophoretic method resulted in the deposition of multiple layers of graphite oxide.

Several nanometer-thick graphene oxide films deposited on silicon nitride-on silicon substrates were exposed to nine different heat treatments (three in Argon, three in Argon and Hydrogen, and three in ultra-high vacuum), and also a film was held at

Polymer-based composites were heralded in the 1960s as a new paradigm for materials. By dispersing strong, highly stiff fibres in a polymer matrix, high-performance lightweight composites could be developed and tailored to individual applications. To

A simple optical method is presented for identifying and measuring the effective optical properties of nanometer-thick, graphene-based materials, based on the use of substrates consisting of a thin dielectric layer on silicon. High contrast between t
