    摘要: Carbon nanostructures are formed from a carbon precursor and catalytic templating nanoparticles. Methods for manufacturing carbon nanostructures generally include (1) forming a precursor mixture that includes a carbon precursor and a plurality of catalytic templating particles, (2) carbonizing the precursor mixture to form an intermediate carbon material including carbon nanostructures, amorphous carbon, and catalytic metal, (3) purifying the intermediate carbon material by removing at least a portion of the amorphous carbon and optionally at least a portion of the catalytic metal, and (4) heat treating the purified intermediate carbon material and/or treating the purified intermediate carbon material with a base to remove functional groups on the surface thereof. The removal of functional groups increases the graphitic content of the carbon nanomaterial and decreases its; hydrophilicity.

    摘要: The carbon nanomaterials and methods relate to methods for causing carbon nanospheres to be readily dispersible in a material. The carbon nanospheres are rendered dispersible using a cationic surfactant. The surfactant includes one or more cationic group that can bond to the surface of the carbon nanospheres, without detrimentally affecting the unique properties of carbon nanospheres. The dispersible carbon nanospheres can be dried (i.e., solvent is driven off) while maintaining their dispersibility in solvents and other materials.

    摘要: The particle sizes of agglomerates of carbon nanospheres are reduced by dispersing the carbon nanospheres in a polar solvent. The carbon nanospheres are multi-walled, hollow, graphitic structures with an average diameter in a range from about 10 nm to about 200 nm, more preferably about 20 nm to about 100 nm. Spectral data shows that prior to being dispersed, the carbon nanospheres are agglomerated into clusters that range in size from 500 nm to 5 microns. The clusters of nanospheres are reduced in size by dispersing the carbon nanospheres in the polar solvent (e.g., water) using a surface modifying agent (e.g., glucose) and ultrasonication. The combination of polar solvent, surface modifying agent, and ultrasonication breaks up and disperses agglomerates of carbon nanospheres.
