A novel conducting polymer-carbon nanotube composite yarn

Conference Paper


Abstract


  • Hybrid polypyrrole (PPy)–multi walled carbon

    nanotube (MWNT) yarns were obtained by chemical

    and electrochemical polymerization of pyrrole on the

    yarn surface. The material was characterized by

    SEM imaging, electrochemical, mechanical and

    electrical measurements. It was found that the hybrid

    PPy-MWNT yarns possess significantly higher

    mechanical strength (over 740 MPa) and Young’s

    modulus (over 54 GPa) and than the pristine MWNT

    yarn. The material also exhibited substantially

    higher electrical conductivity (over 23500 S/m).

    Specific capacitance for PPy-MWNT yarn was

    found over 60 F/g. Measurements of temperature

    dependences of electrical conductivity revealed

    metallic behaviour at high temperature and

    semiconducting behaviour at low temperature with

    the metal-to- insulator transition near 100 K. The

    collected low temperature data are in the good

    agreement with variable range hopping model (3DVRH).

    The improved durability of the yarns is

    important for electrical applications. The composite

    yarns can be produced in commercial quantities and

    used for the applications where the electrical

    conductivity is of primary importance.
