Tessili conduttivi (Conductive textiles)

The polymerisation of pyrrole on a textile substrate using a polyester fabric was investigated. Polymerisation occurs via the formation of cationic radicals following the oxidation of the monomer. The cations formed are coupled to form oligomers which are absorbed on to the surface of the substrate. The conductive properties of the resulting fabric were tested using a voltmeter to measure the surface resistance. The physico-mechanical and thermal properties of the fabric were analysed. A fabric of this type has many possible uses in electronics, reinforcement, protective clothing and military uses, since it combines the physico-mechanical properties of the substrate with the electrical properties of the polypyrrole.
