Graphene is a new two-dimensional honeycomb lattice material composed of single layer sp2 hybrid carbon atoms, which has excellent mechanical, electrical and thermal properties. With its unique properties, graphene has shown great application potential in many fields, and has become a research hotspot in materials science today.
Graphene materials can be divided into the following categories according to the preparation method and morphology:
1. Graphene powder: suitable for composite materials, energy storage devices, etc.
2. Graphene film: suitable for electronic devices, sensors, etc.
3. Graphene solution: suitable for coating, conductive ink, etc.
