USE OF SULPHONIC AND PHOSPHONIC ACIDS AS DOPANTS OF CONDUCTIVE POLYANILINE FILMS AND CONDUCTIVE COMPOSITE MATERIALS BASED ON POLYANILINE

摘要

The invention concerns the use of sulphonic and phosphonic acids functionalised with plasticizing groups as dopants of conductive polyaniline films and conductive composite materials based on polyaniline. Said acids correspond to formula (I) wherein: R<1> represents -SO3H or PO3H2; R<2> represents a linear or branched alkyl group; and m is equal to 1 or 2; or R<2> is a group of formula (II) wherein: R<1> is such as defined in formula (II) and n is an integer ranging between 1 and 16; and m is equal to 1.
