Abstract
A versatile technique for preparing electrically conducting polymer blends is presented which utilizes the soluble precursor approach to conducting polymer synthesis. The water-soluble polymeric sulphonium salt precursor to poly( p-phenylene vinylene) (PPV), a conducting polymer, has been used to prepare blends of PPV with polyacrylamide (PAcr). These phase-separated blends yield flexible and transparent films of good mechanical properties which can be oxidized with strong electron acceptors (e.g. AsF 5) and thereby exhibit greatly enhanced electrical conductivity. The ultimate conductivity shows an atypical gradual composition dependence, which lies between that of the pure components. These blends can also be thermally stretched in the manner reported for pure PPV. Stretching of the PPV/PAcr blends results in highly efficient PPV chain orientation and greatly augmented conductivity along the stretch axis.
