Systems, devices, and/or methods for reactive graphene and its applications

A system comprising:

• a utilitarian substance comprising reactive graphene, said reactive graphene comprising a graphene core that is chemically bonded with a reactive shell, wherein:
• said graphene core is a graphene hybrid composite comprising graphene and one or more of nanocarbon, graphene nanoplatelets, graphene oxide, reduced graphene oxide and pristine graphene;
• said graphene core is prepared via chemical vapor deposition utilizing at least one of a gas, liquid, and solid phase carbon sources;
• and
• said reactive shell carries reactive functional groups that are able to chemically react with other media, wherein said other media is a superconductor, conductor, semiconductor, or insulator, said reactive functional groups comprising electron donor molecules and electron acceptor molecules, wherein:
• said electron acceptor molecules comprise one or more of chemical substituents carrying element S, thiols, sulfides, bisulfides, thiolanes, thiophenes, benzothiophenes, dibenzothiophenes, benzonapthothiophenes, Proxel GXL, triazine, —NO2, —CN, carboxylic acid, sulfonic acid, ketone —CO, hydroxyl —OH, ether —O—, —SO2, —SOCl2, isothiocyanate, aldehyde, acyl azide, anhydride, carbodiimide, epoxide, fluorophenyl ester, carbonate, alkyl, phosphate, alcohol, halide, silanol-SiOH, siloxane, and —SiX, where X comprise one or more of H2, alkyl, aryl, arylene, alkylene, alkoxides;
• and
• electron donor molecules are selected from chemical substituents carrying amino-NR1R2 where R1 and R2 comprise one or more of H2, alkyl, aryl, arylene, alkylene, and phosphorous.
