Description

Internship contract – 6 months | Fulltime/40h | From 01.09.2025 on | Hautcharage Are you passionate about research? So are we! Come and join us

How will you contribute?

The context you will intervene in:

  • Polyurethane (PU) polymers are widely used due to their versatility and high performance. However, their synthesis traditionally involves toxic isocyanates and relies on petroleum-derived monomers, raising significant health and environmental concerns.
  • Non-isocyanate polyurethanes (NIPUs) have emerged as safer and more sustainable alternatives, typically based on the polyaddition of cyclic carbonates and amines. These systems not only eliminate the use of isocyanates but also exhibit improved hydrolytic and chemical resistance, making them promising candidates for bio-based, environmentally friendly materials.
  • At LIST, a novel family of fast-polymerizing polyhydroxyurethane (PHU) materials has been developed thanks to innovative monomers.
  • you will focus on gaining a deeper kinetic and mechanistic understanding of those reactions and potentially unlock new strategies for optimizing them.

Your objectives:

  • Evaluate the reaction kinetics of new monomers.
  • Identify potential rate-limiting steps in the mechanism.

Your tasks and activities:

  • Study reaction kinetics by NMR under varying conditions (temperature, solvent, isotopic substitution).
  • Combine NMR kinetic data with FTIR measurements to support mechanistic interpretations.
  • Analyze experimental data using kinetic modelling to identify possible rate-limiting steps.
  • Study kinetic isotope effects (KIE) by selectively deuterating reactants with D₂O and assessing the impact on the reaction pathway.
  • Use combined spectroscopic approaches (e.g. FTIR) to track structural evolution.

Technics and tools:

  • Wet chemistry techniques for D/H exchange.
  • NMR spectroscopy (¹H, ²H) for kinetic monitoring and structural analysis.
  • FTIR spectroscopy for complementary in situ tracking.
  • Kinetic modelling and activation energy extraction from time-resolved data.
