  2. Hummers' method - Wikipedia

    en.wikipedia.org/wiki/Hummers'_Method

    Hummers' method remains a key point of interest because it is an easy method of producing large quantities of graphite oxide. Other groups have been focused on making improvements to the Hummers' method to make it more efficient and environmentally friendly. One such process is eliminating the use of NaNO 3 from the process.

  3. Graphite - Wikipedia

    en.wikipedia.org/wiki/Graphite

    In art, graphite is typically used to create detailed and precise drawings, as it allows for a wide range of values (light to dark) to be achieved. It can also be used to create softer, more subtle lines and shading. Graphite is popular among artists because it is easy to control, easy to erase, and produces a clean, professional look.

  4. Graphene production techniques - Wikipedia

    en.wikipedia.org/wiki/Graphene_production_techniques

    A rapidly increasing list of graphene production techniques have been developed to enable graphene's use in commercial applications. [1]Isolated 2D crystals cannot be grown via chemical synthesis beyond small sizes even in principle, because the rapid growth of phonon density with increasing lateral size forces 2D crystallites to bend into the third dimension. [2]

  5. Graphene - Wikipedia

    en.wikipedia.org/wiki/Graphene

    In 2002, Robert B. Rutherford and Richard L. Dudman filed for a patent in the US on a method to produce graphene by repeatedly peeling off layers from a graphite flake adhered to a substrate, achieving a graphite thickness of 0.00001 inches (0.00025 millimetres). The key to success was the ability to quickly and efficiently identify graphene ...

  6. Graphene chemistry - Wikipedia

    en.wikipedia.org/wiki/Graphene_chemistry

    Using paper-making techniques on dispersed, oxidized and chemically processed graphite in water, monolayer flakes form a single sheet and create strong bonds. These sheets, called graphene oxide paper, have a measured tensile modulus of 32 GPa. [8] The chemical property of graphite oxide is related to the functional groups attached to graphene ...

  8. Dry lubricant - Wikipedia

    en.wikipedia.org/wiki/Dry_lubricant

    Graphite is characterized by two main groups: natural and synthetic. Synthetic graphite is a high temperature sintered product and is characterized by its high purity of carbon (99.5−99.9%). Primary grade synthetic graphite can approach the good lubricity of quality natural graphite. Natural graphite is derived from mining.

  9. Expandable graphite - Wikipedia

    en.wikipedia.org/wiki/Expandable_graphite

    To produce expandable graphite, natural graphite flakes are treated in a bath of acid and oxidizing agent.Usually used oxidizing agents are hydrogen peroxide, potassium permanganate or chromic acid. Concentrated sulphuric acid or nitric acid are usually used as the compound to be incorporated, with the reaction taking place at temperatures of ...
