Preparative method and application of functionalyzed conducting polymer membranes are described. These functionalyzed polymer membranes are obtained by electrolytic polymerizations of pyrrole, thiophene, furan and aniline in the presence of negatively-charged functional molecules. Incorporations of these anionic functional molecules are driven electrostatically by positive charges of a partially-oxidized polymer membrane matrices during in situ doping process. The resulting poymer membranes/electrodes show a wide variety of functions such as electrochromism, photoelectricity (photocurrent), electrogenerated chemiluminescence, peculier surface function by highly dispersed metal in conducting polymer matrix, membrane sensor and strong mechanical property, which are resulted from functions of incorporated (doped) anionic molecules. A negatively-charged polyelectrolyte incorporated in conducting polymer membrane shows charge-controllable property. In addition, chemically preparative methods for such conducting polymer membranes are described. Those functionalyzed conducting polymer membranes develop new fields of membrane science, with a novel concept of electron transport membrane.
