Processible conducting nanoscale cylinders due to self-organized polyaniline supra molecules

Polyaniline sulphonates contain hydrogen bonding acceptor sites, which allow construction of supramolecules and self-organized structures. Here we have characterized the phase behavior of complexes of polyaniline, camphorsulphomc acid (CSA) and 4-hexylresorcinol (tires), PANI(CSA)(x)(Hres)(y), using small-angle X-ray scattering (SAXS) and electrical conductivity. A hexagonal cylindrical structure with period around 35 Angstrom allows plastication due to the flexible side chains. The conductivity of complexes increased when CSA or tires were added to the nominal complex PANI(CSA)(0.5) indicating that CSA and Hres can be co-solvents for PANI(CSA)(0.5).
