The more a flake is reduced, the more similar it is to graphene than graphene oxide. Reduced graphene oxide can be made by taking graphene oxide, and either chemically reducing or thermally reducing it. Chemically-reduced graphene oxide retains more oxygen-containing functional groups compared to thermally-reduced graphene oxide. It also has the advantage of retaining the flake size and layer ratios of the initial graphene oxide, while having lower defect density than thermally-reduced graphene oxide.

The more a flake is reduced, the more similar it is to graphene than graphene oxide.</p> <p>Reduced graphene oxide can be made by taking graphene oxide, and either chemically reducing or thermally reducing it. Chemically-reduced graphene oxide retains more oxygen-containing functional groups compared to thermally-reduced graphene oxide. It also has the advantage of retaining the flake size and layer ratios of the initial graphene oxide, while having lower defect density than thermally-reduced graphene oxide.</p> <div class="row

Guide</h3> <p>Chemically-reduced graphene oxide has significantly less oxygen-containing groups per flake, making the dispersibility of this material lower than graphene oxide, or nitrogen-doped graphene oxide. Reduced graphene oxide can be dispersed in polar solvents, such as water or DMF.</p> <div class="expandable" id="learn-more"> <p>At Ossila, we have found that the most stable solutions can be produced using the following recipe:</p> <ul> <li>Weigh out desired amount of material, this can go up to around 0.1 mg.ml<sup>-1</sup>.</li> <li>Add 3:2 ratio of isopropyl alcohol to ethylene glycol.</li> <li>Shake vigorously to break up material.</li> <li>For chemically-reduced graphene oxide, use a mechanical agitator instead (as sonication may damage the flakes).</li> <li>For thermally-reduced graphene oxide, a prolonged treatment in an ultrasonic bath can help to break up and disperse the material.</li> </ul> <h3>What is Reduced Graphene Oxide?</h3> <p>When produced, graphene oxide typically has a wide array of different oxygen functional groups present: 1,2-epoxide and alcohol groups on the basal planes, and carboxyl and ketone groups at the edges. Graphene oxide can be readily dispersed in a range of solvents at high concentration, either for additive processing with other materials or for the processing of thick layers. However, graphene oxide does not have the same exceptional physical and electronic properties that make graphene unique. Regardless, graphene oxide can be reduced fully or partially to produce a graphene-like structure by removing the oxygen functional groups present.</p> <p>Reduced graphene oxide can be tuned by varying the degree of reduction, either by using thermal reduction or various forms of chemical reduction. Thermal reduction typically produces a higher degree of reduction than chemical processes, giving higher electrical conductivity. However, due to the high temperatures involved, this can lead to damage of the individual flakes -- either through the breaking of flakes, or through the introduction of defects within the structure. On the other hand, chemical reduction allows for the retention of flake sizes of the graphene oxide used, as well as a lower defects density per flake.</p> </div> <p><button class="anchor expand-link" data-expand-target="learn-more" data-toggle-text="View less" type="button">Learn more</button></p> <h2>References</h2> <hr> <ol> <li> <em>Large-area ultrathin films of reduced graphene oxide as a transparent and flexible electronic material,</em> G.
