Voltammetric Characterisation of Polypyrrole Dodecylbenzenesulphonate

Polypyrrole was deposited from solutions of NaCIO. and NaDDS, wher~ DBS is dodecylbcnzcncsulfonate, in aqueous solu\ion and characterizcd by voltammetry. It is found that the absence of the so-called 'double lavcr charging currcnt ' during cyclic voltammetry of the layers formed from solutions with surfaclant is not because 01' th" order in morphology of the layer , but irreversible incorporation 01' the surfactant anion.
