• Applicant: Professor Dr. Sebastian Seiffert, Ph.D.
• Subject Area: Preparatory and Physical Chemistry of Polymers

• Final Report Year: 2021

Final Report Abstract

The work of this project has realized the proposed target, despite some changes in the way of how this was done. In addition, several side findings were made and followed. In particular, the project has opened marked further perspectives. Future research will especially focus on the role of sticker clustering in transient networks, which was evidenced to play a decisive enforcing role in our work. This may be suitable for the realization of (hydro)gels with both strong mechanics and reversible and therefore degradable connectivity as cyclic soft materials.
