Conforming graphene to a target substrate

A method to conform graphene to a target substrate, the method comprising:

• placing a sheet and the target substrate in a housing, wherein the sheet includes a layer of graphene formed on a transition metal substrate;
• coupling the layer of graphene of the sheet to the target substrate via local extremities of the target substrate within the housing, wherein the local extremities are shaped with points that operate with Van der Waals forces to hold the target substrate in stable contact with the layer of graphene at the local extremities with less than full conformation of the layer of graphene to the target substrate;
• passing an etchant solution through a permeable fabric located within the housing to remove the transition metal substrate from the layer of graphene;
• evacuating the housing to remove air between the layer of graphene and the target substrate;
• and
• applying a hydrostatic pressure to substantially eliminate the local extremities and conform the layer of graphene to the target substrate to form a graphene-on-target substrate assembly.

• passing an etchant solution through a permeable fabric located within the housing to remove the transition metal substrate from the layer of graphene, wherein the permeable fabric is resistant to absorption of the etchant solution;
• evacuating the housing to remove air between the layer of graphene and the target substrate;
• applying a conformal elastomeric coating to an exterior of the housing to seal the housing to protect the target substrate from a fluid located outside of the housing;
• and
• applying a hydrostatic pressure to the housing to substantially eliminate the local extremities and conform the layer of graphene to the target substrate to form a graphene-on-target substrate assembly.
