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.

Abstract: The present invention concerns the use of sulphonic and phosphonic acids, functionalised with plastisizers, as dopants for polyaniline conductor films and polyaniline-based conductive composite materials. These acids meet the following formula: in which: R1 represents —SO3H or PO3H2 R2 is a linear or branched alkyl group and m equals 1 or 2, or R2 is a group having the formula: in which R1 is such as defined above and n is a whole number ranging from 1 to 16, and m equals 1.

Abstract: The invention relates to a method of preparing a conductive composite material, consisting of performing at least one cycle of deposition comprising the following steps: (a) putting an insulating porous substrate (1) in contact with a solution of a conductive polymer such as polyaniline in a volatile organic solvent such as trifluoroacetic acid, and (b) eliminating the organic solvent by evaporation, for forming a deposit of conductive polymer (5) in the pores (3) of the porous substrate.
