Claims14
A reduced graphene oxide structure for stimulation and/or recording of the central and/or peripheral nervous system comprising a stack of layered, reduced graphene oxide flakes, wherein the reduced graphene oxide structure is obtainable by hydrothermal reduction and electrochemically activated in an electrolyte system.
A method for preparing an electrochemically activated and reduced graphene oxide structure, which comprises the following steps:
- providing graphene oxide structure comprising a stack of layered graphene oxide flakes;
- reducing the graphene oxide structure;
- and
- electrochemically activating the reduced graphene oxide structure in an electrolyte system,
- wherein electrochemically activating comprises at least partially sweeping cyclically an electrical potential around a potential equilibrium within a plurality of predetermined ranges.
