Superelastic graphene-based cellular monoliths
|
A novel method for converting natural graphite into highly porous graphene films with advanced applications including energy storage. The highly porous nature of the gel films allows for additional functional materials to be added between the individual graphene sheets, offering opportunity for a range of applications.
- Electrically conductive
- Removal of drying step
- Open and continuous porous structure
- Able to incorporate further functional materials
- Favourable for many practical applications
- Energy Storage (eg. capacitors, batteries and fuel cells)
- LCD displays and photovoltaic devices
- Composites for volatile fuel Storage containers and electronics packaging
- Absorbents for water purification and chemical separation
- Printable conductive inks
The key concept is to process chemically prepared graphene dispersions into a gel film form, instead of dried films or powder that are traditionally adopted. In the graphene gel, individual graphene sheets are interconnected, forming films with a reasonable mechanical strength; each sheet is physically separated by an entrapped liquid or due to its corrugation. Many other functional materials can be added into graphene-based gel films during the synthetic process or by post-addition, to further expand or enhance their applications, significantly reducing the aggregation.
