摘要：

Phenol and several phenol derivatives have been electropolymerised on to platinum anodes. The selective properties of the modified electrodes were dependent on the final polymeric structure. Although essentially nonconducting, dual phenolic films could be deposited on electrode surfaces. This was achieved by the initial deposition of a porous polymer formed from, phenol red, followed by the more diffusion limiting film of oxidised phenol. The resulting composite film showed the combined selective characteristics of the two component polymers. Attempts to enhance polymeric film selectivity via the incorporation of charged or neutral surfactants are outlined. The characteristics of glucose oxidase incorporated into (poly)phenol films are discussed.
