Preparation of carbon nanotube/polyaniline nanofiber by electrospinning

Polyaniline (PANI) is one of the most promising conductive polymers for its cheap and abundant, ease of synthesis, high conductivity and good environmental stability. However the disadvantages, such as insolubility, difficulties in processing and poor mechanical property hinder its application. Carbon nanotube (CNT) was considered as an excellent reinforcing material for its excellent mechanical properties, such as high aspect ratio, high chemical and thermal stability and good conductivity. In this paper, the CNT/PANI composite was prepared from the CNT/aniline nanofiber oxidation, which was obtained by the electrospinning technique. The composite electrochemical performances were characterized by the cyclic voltammogram, galvanostatic charging/discharging and four-probe method. The CNT/PANI composite had excellent application foreground in electrochemical energy field due to large current response, high conductivity and specific capacity.
