• Carbon micro- and nanofibers were prepared by using gyration. • The distribution of fiber diameter showed a normal law with 400-600 nm. • GO changes the orderly arrangement of fibers into a network structure. • The conductivity of carbon nanofibers is greatly improved by adding GO. • When GO was added, the electrode showed excellent electrochemical performance. In this paper, graphene oxide (GO) were added into polyacrylonitrile to prepare carbon nanofiber by using gyration and subsequent carbonization process as to improve their electrochemical properties. The microstructure and electrochemical properties of prepared carbon nanofiber samples were investigated by using scanning electron microscopy and electrochemical workstation, respectively. The effects of the addition amount of graphene oxide and carbonation temperature on the microstructure and electrochemical properties of composite carbon nanofibers were studied.
