A PhD position is available at the University of Twente (the Netherlands) within the MESA+ institute for nanotechnology, and it aims at synthesizing novel bio-based polyamides and polyamines by precise polymerization techniques for chelating agents, gene transfection or self-assembly.
The research goal of the Sustainable Polymer Chemistry (SPC) group is to prepare polymeric materials, additives, and nanocarriers based on renewable resources or with defined end-of-life options (e.g. biodegradation). Our research relies on the designed synthesis of novel monomer and polymer building blocks or utilizes chemically-modified biopolymers. To address the scientific questions we use a combination of experimental techniques including organic synthesis, living polymerization techniques or emulsion formulations. We also use state-of-the-art characterization techniques for polymers and study their polymerization kinetics in detail to control macromolecular function and assembly. Biodegradation or interaction with biological media is also studied for selected materials.
The SPC group is part of the MESA+ Institute for Nanotechnology, which offers advanced characterization and fabrication tools on the nanoscale, as well as a stimulating environment with more than 250 PhD students working on various aspects of nanoscience and technology.
Currently, we are looking for a PhD candidate:
"Bio-based polyamides and polyamines by living anionic polymerization of enantiomerically pure activated aziridines"
Tacticity is one of the most important features of synthetic polymers. The properties of polypropylene, today’s second most-produced polymer, rely on the chirality in the monomer sequence and made it to a commodity. However, it is mainly used as a commodity and not for advanced applications due to several limitations: it carries no additional functional groups, which would control hierarchical self-assembly in solution or be suitable to catalyze organic reactions.
This project will develop a new synthetic platform towards enantiopure polysulfonamides and polyamines, which could not be synthesized before.
i) The living polymerization of activated aziridines leads to well-defined polymers with a variety of functional groups, solubility, and allows combination with other commodity building blocks to prepare complex macromolecular architectures
ii) the starting materials are bio-based amino acids
iv) no limit to certain applications: in the course of this project, several key topics will be studied: self-assembly, asymmetric catalysis, and gene transfection.
For this position we are searching for an ambitious candidate with a Master’s Degree in Chemistry or Materials Science. A solid background in Polymer Chemistry and previous experience in organic synthesis and polymerization are essential. Considering the strongly collaborative nature of the project within the program, we are looking for a team player with good communication skills.
