Abstract
There is provided a method of manufacturing a graphene/graphene oxide layer comprising the steps of: providing a suspension of graphene/graphene oxide in a suspension liquid, applying the suspension on a support, heating the suspension and the support to evaporate liquid to form a layer of graphene/graphene oxide on the support, subjecting the graphene/graphene oxide layer and the support to pressure, and subjecting the graphene/graphene oxide layer to annealing process.
