Jobbannons

We are looking for a highly motivated PhD student to join the research group of Professor Christian Müller. The focus of the project is on understanding the mechanical properties of conjugated polymers and on the development of spinning processes for manufacturing conducting polymer fibers used in wearable electronics. A summary of the research field can be found in a recent review.

Project overview

The aim of the project is to explore the interplay between the electrical and mechanical properties of conjugated polymers and conducting polymer fibers. A central part of the research will involve the development of fiber spinning processes and the integration of the resulting fibers into wearable devices, such as fiber-based organic electrochemical transistors. In addition, tensile testing, dynamic mechanical analysis, nanonindentation and atomic force mircroscopy will be used to characterize the mechanical properties of (doped) conjugated polymers.

You will work closely with fellow PhD students and postdocs at Chalmers, and collaborate with academic and industrial partners in Sweden and internationally. The role also offers opportunities for travel and engagement with external collaborators.

Research environment

The Müller Research Group at the Department of Chemistry and Chemical Engineering of Chalmers University of Technology works at the intersection of physical chemistry and materials science, with a focus on organic semiconductors, polymer blends and composites. The group develops new plastic materials for wearable electronics and energy technologies, including organic solar cells, thermoelectrics, and power cables. All research is conducted in collaboration with other universities, research institutes, and industry. The group currently consists of 1 Professor, 1 Senior Scientist, 5 Postdocs, and 9 PhD students.

Main responsibilities

• Conduct your own research and take doctoral-level courses to develop your scientific and professional skills.
• Present your work and publish your research findings in peer-reviewed scientific journals.
• Contribute approximately 10% of your time to departmental duties, primarily undergraduate teaching.

Qualifications

To be eligible, you must have:

• A Master’s degree in Materials Science, Chemistry, Chemical Engineering, or a related field
• Solid experience in polymer processing and characterization, particularly of solution-processed conjugated polymers
• Excellent collaboration skills
• Strong proficiency in English, both written and spoken.

Merits: Experience in organic electronics and/or fiber spinning is considered a strong asset.

Contract terms

As a PhD student at Chalmers, you are an employee and enjoy all employee benefits. The position is limited to four (4) years, with the possibility to teach up to 10%, which extends the position to 4.5 years. The starting salary is approximately 34'000 SEK per month.
