【摘要】Electrodes derivatized with electroactive polymers or with charged, nonelectroactive polymers can be significantly influenced by the nature of the electrolyte and other ions present in a solution contacted by the derivatized electrode. It has been shown that charged, nonelectroactive polymers can persistently bind significant quantities of charged, electroactive species such as Fe(CN)(6)(4-) by surface polyvinylpyridinium or Ru(bipyridine)(3)(2+) by Nafion. Theses examples illustrate how electrostatic binding may be exploited for anlaysis, preparation of a variety of modified electrodes, and study of electrocatalysis. Electroactive polymers are charged in at least one of their accessible redox states and both selectivity of counterion binding and the movement of ions in and out of the surface polymer associated with change of redox state may affect electrochemical behavior. Electrodes coated with electroactive polymers may have a number of uses, including desalting of H20, that depend on the behavior of solution ions.
