The development of biocompatible and flexible conductive materials has recently received much attention. Poly(3,4-ethylenedioxythiophene) (PEDOT), a representative biocompatible conducting polymer, is electrically conductive. However, it does not meet the criteria of electrical and mechanical performance, to use as electrodes. Thus, doping and reinforcement materials are required. In this paper, Cellulose nanofibers (CNF) were extracted from a natural source, tunicate. Flexible CNF/PEDOT composite was prepared via in situ chemical polymerization. The synthesis of CNF/PEDOT was conducted under various conditions, and the effect of each conditions on the conductivity, morphology and crystallinity of CNF/PEDOT were analyzed. It is expected that the electrically conductive and flexible CNF/PEDOT composite can be used in various fields such as biosensors, implantable electrodes, and electronic tattoos that require biocompatibility.
