Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer f
Figure 3.149.Proposed structure of graphene oxide[356]. The electronic properties of graphene oxide mainly depend on the oxidation level and chemical composition; it can be tailored by removal or addition of certain oxygen groups to adjust the proportion of sp2and sp3carbon[364,365]. Graphene oxid...

Liquid crystal size selection of large-size graphene oxide for size-dependent N-doping and oxygen reduction catalysis. Graphene oxide (GO) is aqueous-dispersible oxygenated graphene, which shows colloidal discotic liquid crystallinity. Many properties of GO-based materials,... KE Lee,JE Kim,UN Mait...
Graphene and graphene derivative nanoplatelets represent a new generation of nanomaterials with unique physico-chemical properties and high potential for use in composite materials and biomedical devices. To date little is known about the impact graphene
Thus, in the medium term, the most promising route is the exfoliation of graphite in the liquid phase to give graphene-like materials. The most common technique has been the oxidation and subsequent exfoliation of graphite to give graphene oxide.6-10 However, this technique suffers from one ...
Graphene fibre is a one-dimensional macroscopic ordered assembly formed by graphene oxide (GO) liquid crystals under unidirectional shear-flow, following by chemical and thermal reduction4,11,14,16. 2D GO sheets flowing in a tubular channel become curved and distorted as a result of the mismatchin...
