PhD position: Correlating redox properties of organic materials with triboelectric charge-separation – from basic understanding to novel materials for efficient triboelectric energy harvesting

Part-time position (65 %), Start-date: At the earliest possible date.

The Cluster of Excellence livMatS develops completely novel, bioinspired materials systems that adapt autonomously to various environments and harvest clean energy from their surroundings. The intention of these purely technical – yet in a behavioral sense quasi-living – materials systems is to meet the demands of humans with regard to pioneering environmental and energy technologies. The societal relevance of autonomous systems and their sustainability will thus play an important role in their development. The research program of livMatS is characterized by highly interdisciplinary collaboration between researchers from a broad range of fields including engineering, chemistry, physics, biology, psychology, the humanities, and sustainability sciences.

Project Description
Charge separation at interfaces is the mechanism underlying the triboelectric effect. This can be exploited to harvest mechanical energy from the surroundings in functional materials systems. In this project novel organic materials will be developed to make triboelectric charge separation more efficient with the ultimate goal to increase the performance of triboelectric nanogenerators used for energy harvesting. This will be preceded by a fundamental study on the effect of the redox activity of organic moieties on triboelectric charge separation by atomic force microscopic (AFM) studies, as well as theoretical investigations (QC) into the physical origins of the charge separation. The results of these fundamental studies will allow selecting the best organic moieties for incorporation into materials (i.e. polymers), which will then be synthesized and used in macroscopic devices to investigate the triboelectric charge separation at their interfaces.

The position is located at the Institute for Organic Chemistry at the University of Freiburg (group of Prof. B. Esser), and the project will be carried out in close collaboration with the Institute for Physical Chemistry (Dr. B. Balzer) and the Technical Faculty (Prof. P. Woias, Prof. J Rühe, Prof. M. Moseler, Dr. M. Walter).
