CHEMICAL PROCESS FOR GRAPHENE TRANSFER FROM ONE SUBSTRATE TO ANOTHER
The invention relates to a process for the transfer of graphene grown on a copper substrate, by chemical vapour deposition (CVD), onto another substrate. According to the invention, the process consists in depositing a film of polymethyl methacrylate (PMMA) onto the graphene/copper substrate, follow...

| description | The invention relates to a process for the transfer of graphene grown on a copper substrate, by chemical vapour deposition (CVD), onto another substrate. According to the invention, the process consists in depositing a film of polymethyl methacrylate (PMMA) onto the graphene/copper substrate, followed by a heat treatment at 120°C, for 2 min, etching the copper substrate in a HCl:HO:HOsolution, in the presence of hexane, at the ambient temperature, and washing with deionized water, after which the transfer of the graphene/PMMA layer onto the substrate of interest takes place, followed by a heat treatment at 120°C, for 2 h, and by the removal of the PMMA and by the final treatment at 180°C, for 2 h. |
