| 英文摘要 | carbon nanofibers (cnfs) have a wide range of applications and are commonly prepared under harsh conditions with small quantities. a green method for the preparation of cnfs under mild conditions with the scalable potential is highly challenging. here, we describe a facile water-based room-temperature approach to producing gel fibers from a perylene diimide derivative via self-assembly, gelation, freeze-drying, and then to generating cnfs by subsequent pyrolysis under ar. the entangled cnfs, with relatively uniform diameters around 20-50 nm, can be prepared as thin films or monoliths. the cnfs doped with elements n and sn can be readily produced. the cnfs are characterized by various techniques and particularly evaluated as electrode materials for supercapacitor by cyclic voltammetry and galvanostatic charge-discharge. a non-ionic surfactant (pluronics f-127) can be easily incorporated into the self-assembly process, which produces the cnfs with a higher surface area 520 m(2) g(-1) and a specific capacitance of 346 f g(-1) at the scan rate of 1 mv s(-1) or 192 f g(-1) at the current density of 1 a g(-1). the cnf electrodes are highly stable. quite surprisingly, the specific capacitance increases with repeated testing, achieving an impressive 226 f g(-1) for 1000 charge/discharge cycles at 4 a g(-1). |
