About us

The DWI – Leibniz-Institute for Interactive Materials is a federal and state funded research institute of the Leibniz Association based on the Melaten Campus of RWTH Aachen University. International young and experienced scientists from various disciplines develop interactive materials based on the principles of nature. It is a location at which people with different talents, experiences and skills work together, in order to learn from one another and generate new knowledge and new methods to create a better quality of life in our world.

DWI offers you a wide range of possibilities to develop further both professionally and personally in an interdisciplinary setting.

Position

DWI invites applications for a position as

PhD student (f / m / d) in the field of polymer chemistry and physics

Starting from now, a PhD student position is available in the research group of Dr. Jian Wang, an independent group leader of DWI. The research in his group aims to open new frontiers in multiple scientific disciplines ranging from interface and macromolecular chemistry to drug delivery and cancer therapy technology and seeks to make significant contributions to both fundamental science and practical applications, potentially offering solutions to some of the world's most pressing issues in sustainability and healthcare.

Your tasks

A brush structure is formed when polymer chains are anchored to a surface at high tethering densities. Attaching the chain ends to a surface effectively fixes the characteristic length between polymer chains, which leads to behavior that is not found with free chains. This unique structure of polymer brushes affords them many important applications, such as the steric stabilization of colloidal systems and lubrication. Our group has reported the observation of pyro- and piezoelectricity in thin surface-attached polymer brushes containing zwitterionic and electrolytic side groups. The observed piezo- and pyroelectric properties are attributed to a complex interplay of the non-uniform segment density within these films, together with a non-uniform distribution of counterions and specific ion effects but there is no direct evidence supporting this theory.

The task of this job is to investigate the fundamental question of how the counterion is influencing the piezoelectric property of the polyelectrolyte (PE) polymer and explore the interaction of focused ultrasound on PE brushes, and utilize the new piezoelectric effect to design redox responsive systems for biomedical applications.

Your profile

• Completed studies (M.Sc. or comparable) in organic chemistry, polymer chemistry, catalysis chemistry or materials science.
• Highly motivated and team oriented
• Passion for multidisciplinary research and being eager to learn new techniques
• Strong research background in organic chemistry and polymer science.
• Excellent skills in the English language
