Abstract
Methods for reshaping graphene oxide sheet-containing structures using water are provided. Graphene oxide sheet-containing structures can be reshaped by applying a force to a graphene oxide sheet-containing structure, wherein the force changes the initial shape of the structure to a new shape. While the force is still acting on the graphene oxide sheet-containing structure, liquid water is applied to the structure to dissipate stress induced by the force and the structure is then dried. When the force is removed, the graphene oxide sheet-containing structure remains fixed in the new shape.
Claims16
A method of reshaping a structure comprising graphene oxide sheets, the method comprising:
- applying an external force to the structure, wherein the external force changes the shape of the structure from a first shape to a second shape;
- applying water to the structure while it has the second shape;
- drying the structure;
- and
- removing the external force, wherein the dried structure remains fixed in the second shape after the external force is removed.
A method of bonding a first structure comprising graphene oxide sheets to a second structure comprising a co-dispersion of graphene oxide sheets and a particulate material, the method comprising:
- bringing the first structure and the second structure into contact in a contact area;
- applying liquid water to the contact area;
- and
- drying the first and second structures, whereby the first and second structures are bonded together.
