Abstract Scope |
Carbon nanofibers (CNFs) exhibit great potentials in the fields of electrochemical energy devices because of their extremely large surface areas, good conductivity, excellent chemical resistance and structural stability. However, the conductivity of CNFs originated from spinning of polyacrylonitrile is usually low due to their pyrolytic porous structure. Herein, conductive ceramic MAX-phase Ti3AlC2 encapsulated carbon nanofiber (CNF@MAX) was fabricated by sequential electrospinning, pre-oxidation, radio frequency (RF) magnetron sputtering and carbonization process. Thickness-controllable Ti3AlC2 was successfully coated on the surface of carbon nanofibers by precise control of sputtering power and time, which have unique structural and electrochemical performance advantages. The Ti3AlC2 coating showed excellent electrical conductivity, chemical and thermal stability, and strong interfacial bonding with carbon nanofibers. This work offers a feasible way to hybrid MAX phase ceramic coatings on carbon materials, which can be used as potential electrodes for advanced energy storage devices. |
