Description of the thesis topic
With rising energy costs and our growing arsenal of touch pads, smartphones and portable medical monitors, we are always on the lookout for new ways to power our devices. There is also a huge market for sportswear to optimize human performance. What if we could power our mobile devices, connected watches and medical devices with our simple body heat through light, inexpensive and flexible thermoelectric devices? Organic thermoelectricity is a booming field. We have recently demonstrated that it is possible to achieve electrical charge conductivities within polymeric materials as large as Copper, thanks in particular to the control of both the structure and the doping of semiconducting polymers in thin films.[1,2]
This project focuses on bulk polymeric materials of high void fraction (polymeric aerogels). In particular, the low thermal conductivity of aerogels should be used to increase the thermoelectric performance of polymers.
The BODYTEG project thus proposes to develop conductive polymer aerogels (CPA). To meet this challenge, the project is based on four main objectives that will have to be addressed by the doctoral student: i) develop new CPAs of controlled morphology, ii) take advantage of the porosity of the network to reduce thermal conductivity, iii) maintain good mechanical and electrical properties, iv) correlate the structure of these new CPAs with their electrical and thermal properties.

This thesis work will be carried out at the Charles Sadron Institute, whose research activities focus on polymer materials and self-assembled systems. The laboratory's website can be consulted for details on its activity: https://www-ics.u-strasbg.fr/#&panel1-1&panel1-1
The doctoral student will be attached to the ED182 doctoral school: Physics and Chemistry- Physics at the University of Strasbourg: http://edpcp.u-strasbg.fr
He/she will work within the SYCOMMOR team (Molecular and Organized Macromolecular Complex Systems).
This thesis work will be carried out within the framework of Laure Biniek's ANR JCJC BODYTEG.
Constraints and risks
No particular risks.
A young chemist/physico-chemist who is highly motivated by an innovative subject with a solid background in polymer science is actively sought. Skills or an internship in organic electronics (photovoltaics, thermoelectricity, charge transport), or structural studies would be appreciated. He/she must be open-minded and curious, able to work in a team, rigorous and have strong laboratory skills.
Please provide with your application a full CV (with one or two reference contacts), a cover letter and the transcript of marks from the last year of the Master's degree course.
