Research Abstract

Survey of possible superconductivity in polymers
Possibility of superconductivity in the polymers was surveyed by use of high pressure. i) Polypyrrole(+PF_6), ii) P3HexTh(+In-), iii) PDA(polydiacetylene), iv) PEDOT(PF_6 doped). Since these materials did not show divergent resistivity down to low temperature, we expected pressure to suppress resistivity, but the examined samples did not show lowerering the resistivity.
