Elucidating double network hydrogel fracture using optical force probes

Working group: RG Göstl

Gain insight into the fracture mechanism of double network hydrogels (DNHs) by analyzing the damage region. You will be involved in the synthesis and utilization of the π-extended anthracene force probes to visualize microstructural damage within DNHs.

Project description
The RG Göstl is investigating mechanoresponsive polymer materials. This project’s primary objective is to gain a comprehensive understanding of the fracture mechanics of DNHs which lies in analyzing the damage region. Collaborating with the Department of Continuum Mechanics (CM) of RWTH Aachen University and the Leibniz Institute of Polymer Research (IPD) Dresden you will develop a mechanofluorochromic DNH system that facilitates the visualization crack propagation within the structure, thereby enabling the direct indication of microstructural damage.

Your tasks and responsibilities
You will be responsible for the synthesis of π-extended anthracene mechanofluorophores and their integration as co-crosslinkers into PNIPAAm hydrogels. Your role will include a comprehensive examination of the various parameters associated with the DNH manufacturing process. Additionally, you will conduct mechanical characterization and optical fracture analyses of the produced DNHs as part of your responsibilities.

Therefore, you must be a motivated chemistry student interested in bringing small molecule function to the material level. Ideally, you excel in synthetic organic and polymer chemistry.

This is what we offer

  • Opportunity to write your thesis or student internship report in a unique team working at the interface of organic and polymer chemistry
  • Collaboration with mechanical analysis (IPF) and theory (CM) to see your work through multiple stages of research
  • An inclusive and team-oriented work environment in an international, dynamic setting
  • The guidance and support of an experienced team

We look forward to receiving your application!
