In some embodiments, the present disclosure pertains to methods of producing a graphene hybrid material by exposing a graphene precursor material to a laser source to form a laser-induced graphene, where the laser-induced graphene is derived from the graphene precursor material. The methods of the present disclosure also include a step of associating a pseudocapacitive material (e.g., a conducting polymer or a metal oxide) with the laser-induced graphene to form the graphene hybrid material. The formed graphene hybrid material can become embedded with or separated from the graphene precursor material. The graphene hybrid materials can also be utilized as components of an electronic device, such as electrodes in a microsupercapacitor. Additional embodiments of the present disclosure pertain to the aforementioned graphene hybrid materials and electronic devices.

In some embodiments, the present invention provides methods of making graphene-carbon nanotube hybrid materials. In some embodiments, such methods generally include: (1) associating a graphene film with a substrate; (2) applying a catalyst and a carbon source to the graphene film; and (3) growing carbon nanotubes on the graphene film. In some embodiments, the grown carbon nanotubes become covalently linked to the graphene film through carbon-carbon bonds that are located at one or more junctions between the carbon nanotubes and the graphene film. In some embodiments, the grown carbon nanotubes are in ohmic contact with the graphene film through the carbon-carbon bonds at the one or more junctions. In some embodiments, the one or more junctions may include seven-membered carbon rings. Additional embodiments of the present invention pertain to graphene-carbon nanotube hybrid materials that are formed in accordance with the methods of the present invention.
