Abstract: In order to explore the role of conductive materials in the repair of peripheral nerve injuries, so as to develop a conductive nerve catheter that can replace autologous nerve transplantation, relevant researches at home and abroad in recent years are reviewed. The mechanism of electrical stimulation to promote axon regeneration and the nerve regeneration on conductive substrates are discussed. The application of conductive materials such as polypyrrole, polyaniline, and graphene in nerve conduits is introduced, including the composite method of conductive materials on the conduits, application characteristics, in vitro and in vivo test results, etc. It is pointed out that in the future research on conductive nerve conduits, we should pay attention to and solve the problems of conductive materials that are difficult to process and hard to degrade, as well as the long-term metabolic mechanism and physiological toxicity of conductive materials in vivo and their role in long-distance nerve injury repair.
