Use of sulphonic and phosphonic acids as dopants of conductive polyaniline films and conductive composite material based on polyaniline

摘要

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.
