  • Patent number: 8535570
    Abstract: The present invention relates to a process for the preparation of a conductive polymer composition comprising the steps of A) providing a latex containing a conductive polymer; B) mixing the latex from A with either an aqueous latex of a polymer, or with (a) water-soluble precursor(s) of a polymer; C) removing water from the so obtained mixture; D) heating the product from step C) to a temperature at which the polymer added in step B flows or where the polymer introduced in step B is formed from out of its precursor(s); and E) processing and/or solidifying the product of step D) into a desired form, wherein the amount of conductive polymer is between 0.1 and 10 wt % relative to the total of the total of components in step A and B. In step A optionally carbon nanotubes (CNTs) in an aqueous medium are preferably added to the latex containing conductive polymer. In that case the conductive polymer may behave as a conductive polymeric surfactant for the CNTs dispersed in water.
