Next generation n-doped conducting polymers

Purpose and goal

The purpose of this research project was to develop novel n-doped (electron-transporting) conducting materials with the ultimate goal to assess their potential application in large area printed energy harvesting and storage technologies. The overall mission of this project was also to prepare the fellow to become an independent scientist via world-class training through research in the supra-sectorial field of organic electronics, and to establish a long-term collaboration with one of the most prominent international R&D company in organic semiconductors.

Expected results and effects

The project resulted in the discovery of new polymers that can be easily printed from solution, at low cost, on a variety of substrates including soft and conformable materials. The newly discovered polymers were appropriately designed to be doped efficiently by commercially-available molecular dopants, and to be able to sustain high current without degradation. This resulted in n-doped polymers yielding record-high conductivities, high heat-to-electricity conversion efficiency and high charge storage capability.

Planned approach and implementation

The project consisted of two phases: an outgoing phase that was conducted in Chicago - USA, and a return phase that was carried out at Linköping University. During the outgoing phase in USA, the fellow was involved in and guided several research activities regarding the design and development of novel n-doped conducting polymers, as well as the testing of energy harvesting devices made thereof. Part of this research was carried out at Flexterra-Polyera and in collaboration the group of Prof. T. Marks at Northwestern University, where Flexterra-Polyera sponsor research activities.
