Map ESR Project 4


  • Comparison of sequential doping, vapor doping and co-processing of polymer-dopant pairs; characterization of TE properties
  • Dopant diffusion and thermal stability
  • Use techniques to uniaxially align conjugated polymers, both in thin films (alignment layers, epitaxial & directional crystallization, rubbing) and bulk (tensile drawing, fiber spinning and solid state pressing)
  • Influence of energy levels and of dielectric constant on doping efficiency and charge transport

Expected results

  • Doped polymers with optimized and thermally stable TE performance
  • Improvement of TE performance through uniaxial alignment
  • Enhanced doping efficiency using polar polymers with a low ionization energy

Skills acquired

  • Understanding of key polymer science concepts and doping chemistry, polymer processing techniques
  • TE characterization techniques
