摘要：
Electrochemical a.c. impedance measurement is carried out for polyacenic semiconductive (PAS) materials prepared by pyrolytic treatment of phenol-formaldehyde resin in order to investigate the electrochemical doping mechanism at the interface between electrode and electrolyte. The ionic relaxation model is introduced to understand the present results. It is concluded that more than half of the dopants are trapped in the PAS electrode with relatively weak interaction, the relaxation time of which is 53 s. This is closely connected with the fact that the PAS battery possesses rapid charge-discharge characteristics.
