ABSTRACT:
A conductive polymeric composite with an improved electrical activation density obtained by compounding a ferrocene derivative used as a dopant with a polypyrrole of a conductive polymer and a method for preparing the same. The conductive composite can be produced by use of a chemical method or an electrochemical method. In the case of using the chemical method, pyrrole or its derivative is dissolved in a solution containing a ferrocene derivative, together with one or mixture of ferric trichloride, ammonium persulfate and copper chloride-aluminum chloride. In the case of using the electrochemical method, a solution, in which pyrrole or its derivative is dissolved together with ferrocene derivative, is used, as an electrolytic solution, alone or together with a solution in which an electrolyte of inorganic salt such as ammonium salt, lithium perchloric acid and tetraalkylammonium perchloric acid is dissolved. The composite is a superior conductive composite exhibiting an electrochemical activity by virtue of reversible oxidation-reduction reaction of conductive polymer itself and having a high density of electrochemically active material by virtue of an addition of an electrochemical activity obtained by the oxidation-reduction reaction of ferrocene added as an electrolyte.
