Electrically conductive polymers, especially polypyrroles, are formed with a charged polymeric dopant supplying the necessary counter-ions to stabilise the charged conductive form of the conductive polymer. The physical properties of the conductive polymer can thus be usefully modified in ways different from those achieved by non-polymeric dopants or by forming the conductive polymers in pre-existing bodies of non dopant (i.e. uncharged) polymers. Examples of the dopants which can be used are ionisable polysulphonate, poly(2- acrylamido-2-methylpropane sulphonic acid), sulphonated poly(2,5- dimethylphenyleneoxide), sulphonated polystyrene, sulphonated polyethylene, sulphonated styrene (hydrogenated) butadiene copolymer and ionisable polycarboxylate or polyphosphonate. |
