Poly(3, 4‐ethylenedioxythiophene)/poly(styrene sulfonate) (PEDT/PSS) composite is prepared by solution polymerization at room temperature in the presence of 3, 4‐ethylenedioxythiophene as the monomer, PSS as the doping agent, potassium supersulfate (KPS) as the oxidant, and deionized water as the solvent. The color of the PEDT/PSS solution is dark blue and its solid content is 2.2%, its pH value is 1.5. By mixing alcohols, polar organic solvents, adhesives, and so on into PEDT/PSS solution, the anti‐static coating solution is prepared. The coating is conducted by bar‐coating (20 µm) at 40% relative humidity and 20°C. The influence of the content of each component on the coating surface resistivity is discussed, and a reasonable volume content of each component is obtained. The obtained coating has low surface resistivity (1 × 10 6 Ω), excellent water resistance, and high transmittance of visible light together with a wide range of potential applications.
