WebGraphitization of polymers is an effective way to synthesize nanocrystalline graphene on different substrates with tunable shape, thickness and properties. The catalyst free synthesis results in crystallite sizes on the order of a few nanometers, significantly smaller than commonly prepared polycrystalline graphene. WebCatalytic graphitization is broadly defined as the “transformation of non-graphitic carbon into graphite by heat treatment in the presence of certain metals or minerals”. 11 The process normally occurs at a much lower temperature than graphitization without a catalyst, which makes it attractive from both an environmental and economic perspective.
