Titre : Postdoc position on Dynamics and structure of polymers in deep eutectic solvents
Responsable : Vahdati Mehdi (PECMAT)
Description du projet
Deep Eutectic Solvents (DES) are an emerging class of green, "designer" solvents formed due to hydrogen bonding interactions between hydrogen bond donor and acceptor species at specific compositions. Research from our group shows that model polymer networks swollen in a DES exhibit enhanced nonlinear mechanical properties compared to their counterparts in conventional solvents. Molecular dynamics simulations suggest that specific solvent-polymer interactions play an important role in the modification of the bulk properties. This project aims to cast light on the structure and dynamics of model polymer solutions based on deep eutectic solvents in an attempt to explain the role of the solvent in the bulk mechanical properties of polymer gels. Solutions of model polymers in DES will be studied via viscosity measurements to determine the concentration regimes and the relevant scaling behaviors. A similar investigation will be performed via X-ray scattering to establish structure-properties relationships. The results will be compared with molecular dynamics simulations (performed by a collaborator). Polymer solutions and gels will be compared to elucidate the role of solvent-polymer interactions.
Informations complémentaires
Curious and interactive Ph.D. graduates in polymer physics or physical chemistry, soft matter mechanics, or materials science are encouraged to apply. Previous experience in rheology and scattering will be an advantage. Experience in polymer chemistry is not required but will be a plus. Fluent communication in English is a requirement.
