  • Sulphonic acids as dopants for polyaniline and for conductive polyaniline-based composite materials
    Patent number: 7390439
    Abstract: The invention relates to the use of sulphonic, phosphonic and phosphoric acids functionalized with plasticizing groups as dopants for conductive polyaniline films and for conductive polyaniline-based composite materials. These acids correspond to the following formula (I): in which: R1 represents —SO2(OH) or —PO(OH)2 or —OPO(OH)2; the R2 groups, which are identical or different, represent a hydrocarbonaceous group, such as a 2-ethylhexyl, butoxyethyl or isopropylbenzyl group; R3 and R4 independently represent a direct bond or a hydrocarbonaceous group, such as a methylene group.
    Type: Grant
