Graphene foam

Product Name

^{Name:Graphene foam}

Product Overview

^{Graphene foam presents a three-dimensional network structure similar to foam. It is composed of numerous interconnected graphene layers, which interweave and construct rich pores. The size of pores varies from nanometer to micrometer, presenting a highly open and interconnected structure as a whole. The preparation of graphene foam film by CVD method is usually carried out at high temperature (usually several hundred degrees Celsius to over one thousand degrees Celsius) and specific atmosphere (such as carbon containing gas, etc.), where the carbon source gas is decomposed and carbon atoms are grown on the substrate to form graphene under the action of a catalyst. Then, by controlling the growth conditions and subsequent treatment, graphene can form a three-dimensional foam structure. For example, using copper foil as the substrate and methane as the carbon source gas, the reaction is carried out in a high-temperature furnace. Firstly, methane decomposes at high temperatures to produce carbon atoms, which deposit on the surface of copper foil and gradually form graphene layers. Then, by controlling parameters such as reaction time and gas flow rate, graphene sheets are interconnected and grow into three-dimensional foam structures. Finally, the graphene foam is transferred from the substrate to obtain an independent graphene foam material.}
