Objectives
- 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
