Polyphenol film deposited on platinum foil can continuously grow with time during the electrolysis of a phenolsolution consisting of 0. 1 mol L~(-1) phenol, 3 mol L~(-1) NaOH and 0.5 mol L~(-1) Na_2SO_4, as has been proved by the methods ofsweep potential, constant potential and constant current, and visible spectra during the electrolysis of phenol. A polyphenolfilm with thickness of 0.11 mm was obtained by the electrolysis of phenol at a constant potential of 0.70 V (versus Ag/AClwith saturated KCl solution). Polyphenol film is inactive and stable in 2 mol L~(-1) H_2SO_4 solution, neutral solution and3 mol L~(-1) NaOH solution and in the potential range between -0.95 and 1.35 V. The usable potential range is dependent onthe pH value. Polyphenol has an ESR signal with a g factor of 2.0049. The conductivity of polyphenol is 1.2×10~(-4) S cm~(-1). Inthe solution of polyphenol dissolved in DMSO, the mobility of polyphenol anions is 8×10~(-9) m~2 s~(-1) V~(-1) at 20℃.
