5. A method of preparing a chemically responsive polymer film, comprising:
obtaining a chemically responsive polymer film including at least one of a polaronic conjugated homopolymer including a monomer represented by the following Chemical Formula 1 and a polaronic conjugated block copolymer including the monomer represented by the following Chemical Formula 1 and a monomer represented by the following Chemical Formula 2:

OG Complex Work Unit Chemistry
wherein in the above Chemical Formula 1,
R1 is a linear or branched alkyl group having 1 to 8 carbon atoms,
wherein the chemically responsive polymer film exhibits different structural colors depending on a redox state and/or a thickness, and
wherein the chemically responsive polymer film exhibits a change in structural color depending on a standard reduction potential, basicity, vapor pressure of a reducing gas, a reducing solution, an oxidizing gas, an oxidizing solution, or surface properties of a substrate..
