Abstract: Disclosed herein is a method of synthesizing a conducting polymer using a polymer, having a substituent in a part, as a dopant, in which a variety of polymers is substituted with a predetermined functional group to serve as a dopant such that the substituted functional group functions as the dopant of the conducting polymer, or a monomer having a substituent able to act as a dopant is copolymerized to prepare a polymer dopant having a substituent in a part thereof. The partially substituted polymer dopant may serve as a dopant upon synthesis of the conducting polymer or upon additional doping of the synthesized polymer. Compared to a conventional monomer dopant, the polymer dopant does not emit low-molecular-weight material, and has higher solubility. Further, compared to a polymer dopant having a substituent such as a sulfonic acid group throughout, the synthesized conducting polymer can have superior mechanical properties and maximum conductivity.
