摘要： The present disclosure is directed to methods for altering the surface of carbon fibers by growing carbon nanotubes thereon. Coverage of the carbon fibers by carbon nanotubes provides increased surface area and aspect ratio, as well as provides high electrical and thermal conductivity. In some embodiments, the surface of the carbon fibers are further modified via argon-ion bombardment or plasma treatment to provide controllable defects and to allow for easier growth of carbon nanotubes on the surface of the carbon fibers.

摘要： A simple approach to produce mixed Cu/Cu2O nanocrystals having a specific morphology by controlling the reaction temperature during Cu/Cu2O nanocrystals synthesis. Other variables are kept constant, such as the amount of reactants, while the reaction temperatures is maintained at a predetermined temperature of 70° C., 30° C. or 0° C., which are used to produce different and controlled morphologies for the Cu/Cu2O nanocrystals. The reaction mixture includes a copper ion contributor, a capping agent, a pH adjustor, and reducing agent. The reaction mixture is held at the predetermined temperature for three hours to produce the Cu/Cu2O nanocrystals. The synthesis method has advantages such as mass production, easy operation, and high reproducibility.
