    摘要: In some embodiments, the present disclosure pertains to methods of forming cross-linked carbon materials by: (a) associating a sulfur source with carbon materials, where the sulfur source comprises sulfur atoms; and (b) initiating a chemical reaction, where the chemical reaction leads to the formation of covalent linkages between the carbon materials. In some embodiments, the covalent linkages between the carbon materials comprise covalent bonds between sulfur atoms of the sulfur source and carbon atoms of the carbon materials. In some embodiments, the chemical reactions occur in the absence of solvents while carbon materials are immobilized in solid state. In some embodiments, the carbon materials include carbon nanotube fibers. In some embodiments, the methods of the present disclosure also include a step of doping carbon materials with a dopant, such as iodine. Further embodiments of the present disclosure pertain to cross-linked carbon materials formed in accordance with the above methods.
