By employing biomimetic approaches, some exceptional properties and structures found in nature can be mimicked in graphene materials, effectively enhancing graphene's adsorption and mechanical properties. Current biomimetic methods include biomimetic mineralization, self-assembly, and templating. unfortunately, all of the above methods suffer from the disadvantages of complexity and poor bionic effect.
