  • Conductive polymer doped by a sulphonated cyclodextrin salt and device for obtaining and/or supplying an active substance incorporating said polymer
    Patent number: 5587466
    Abstract: Conductive polymer doped by a sulphonated cyclodextrin salt and device for obtaining and/or supplying an active substance incorporating said polymer.The dopant used has the following formula (I): ##STR1## in which n is an integer between 2 and 50, M.sup.+ is Na.sup.+, Li.sup.+, K.sup.+ Mg.sup.+ 1/2 or NH.sub.4.sup.+ and R represents --SO.sub.3.sup.- M.sup.+ or --OH, whereby R can differ from one cycle to the other. The doped conductive polymer can be used as an active electrode material in an electrochemical device.
