Abstract
The present invention relates to a conductive polymer. The present invention provides a conductive polymer substituted with acid labile functional group comprising an amine functional group and acid labile functional group which plays a protecting role substituted to the amine functional group of a conductive polymer. The conductive polymer of the present invention has enhanced physical and mechanical properties with higher solubility and conductivity than a conventional polyaniline or polypyrrole composition, and also, has improved transparency, sensitivity, adhesive property and patternability. Moreover, the conductive polymer of the present invention has the higher electrical conductivity of the minimum 10 times and the most maximum 102 S/cm than the previous polyaniline, and accordingly, can be used for photosensitive material such as fiber, coating, electrode, organic semiconductor and the like.
