A series of new conducting interpenetrating polymer networks (IPNs) are prepared by sequential crosslinking reactions of tetraethyl orthosilicate with silicon‐grafted functional styrene‐isoprene‐styrene triblock copolymer (SIS) and polyaniline (PANI) doped with dodecylbenzenesulfonic acid (DBSA). The various factors affecting the properties of conductive IPNs are investigated. The conductivity is found to increase only slightly after the IPN films are treated at 140 ° C . The thermal stability of the IPNs is much better than that of the pure polymer under nitrogen atmosphere, as shown by the results from thermal gravimetry analysis (TGA). © 1999 Society of Chemical Industry
