NOVELTY - A conjugated polymer-surfactant complex comprises an electrical percolation threshold of less than about 10 wt.% when the conjugated polymer-surfactant complex is incorporated into a non-conducting matrix, where the conjugated polymer-surfactant complex comprises a conjugated polymer and a surfactant associated with the conjugated polymer, where the surfactant is selected from a 6-16C alkyl sulfonate, a 6-16C alkyl sulfate, a 6-16C alkylbenzenesulfonate, and its combination.    USE - The conjugated polymer-surfactant complex is useful for preparing corrosion-reducing composite and battery (all claimed). It can also be used as coating and as paint additive.    ADVANTAGE - Conjugated polymer-surfactant complexes that can provide a stable dispersion or gel, are provided.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a corrosion-reducing composite comprising the conjugated polymer-surfactant complex and a corrosion-reducing material;    (2) a battery comprising the conjugated polymer-surfactant complex; and    (3) a process of making a conjugated polymer-surfactant complex, which involves: (a) providing a mixture, comprising: (i) an organic solvent; (ii) a surfactant selected from a 6-16C alkyl sulfonate, a 6-16C alkyl sulfate, a 6-16C alkylbenzenesulfonate, and its combination; (iii) a transition metal cation; and (iv) a monomer selected from 3,4-ethylenedioxythiophene, thiophene, pyrrole, aniline, and its substituted derivatives; and (b) reacting the mixture to provide a conjugated polymer-surfactant complex comprising a conjugated polymer comprising 3,4-ethylenedioxythiophene, thiophene, pyrrole, or its combination, where the conjugated polymer-surfactant complex has an electrical percolation threshold of less than about 10 wt.% when the conjugated polymer-surfactant complex is incorporated into a non-conducting matrix, where the conjugated polymer-surfactant complex comprises a conjugated polymer and a surfactant associated with the conjugated polymer, where the surfactant is selected from a 6-16C alkyl sulfonate, a 6-16C alkyl sulfate, a 6-16C alkylbenzenesulfonate, and its combination.
