Three-dimensional (3D) graphene has huge application potential and existing preparation technology needs to be optimized.

Three-dimensional graphene (3D graphene) is a new type of carbon nanomaterial composed of two-dimensional graphene on a macro scale. Three-dimensional graphene has the characteristics of high specific surface area, excellent mechanical properties, ultra-high electrical conductivity, and high thermal conductivity. It is widely used in thermal interface materials, data centers, new energy, construction, electrochemical energy storage,…
