Graphene oxide sheets at interfaces.
Graphite oxide sheet, now called graphene oxide (GO), is the product of chemical exfoliation of graphite and has been known for more than a century. GO has been largely viewed as hydrophilic, presumably due to its excellent colloidal stability in water. Here we report that GO is an amphiphile with hydrophilic edges and a more hydrophobic basal plane. GO can act like a surfactant, as measured by...
متن کاملGraphene oxide as surfactant sheets*
Graphite oxide sheet, now referred to as graphene oxide (GO), is the product of chemical oxidation and exfoliation of graphite powders that was first synthesized over a century ago. Interest in this old material has resurged in recent years, especially after the discovery of graphene, as GO is considered a promising precursor for the bulk production of graphene-based materials. GO sheets are si...
متن کاملLangmuir - Blodgett Assembly of Graphene Oxide Sheets
Introduction Graphene oxide is the liquid oxidation of graphite powder, and consists of a single atomic carbon network derivitized by phenol hydroxyl and epoxide groups on the basal plane and carboxylic acid groups at the edges[1, 2]. The chemical functionalization breaks the extended π−π conjugation of graphene, resulting in an insulating material. However the conductivity may be partially res...
متن کاملHighly Confined Phases of Graphene Oxide Sheets
The graphene oxide (GO) is widely used as a graphene precursor. It has been recently evidenced that this object can form different lyotropic liquid crystals phases observed in highly anisotropic colloids. The confinement of GO sheets, a two-dimensional (2D) crystal is herein aim of study. The binary GO water is studied to describe the liquid crystallinity of concentrated dispersions, characteri...
متن کاملGraphene Oxide Antibacterial Sheets: Synthesis and Characterization (RESEARCH NOTE)
Graphene oxide (GO) was synthesized by oxidation of graphite powder using a time-saving modification of Hummers’ method and its antibacterial activity was investigated. Different techniques were applied to characterize the synthesized GO. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) were used to investigate the crystallinity, morphology, topograp...
