Description of the thesis topic
This Ph.D. thesis is part of an ANR project, NCO-innov, whose objective is to develop new methods to access isocyanates and their derivatives, urethanes and polyurethanes (PU), from cheap and notably bio-sourced raw materials. PU is a widely used class of commodity polymers prepared industrially by adding polyols to polyisocyanates. As the latter are carcinogenic, new routes to PU must be considered.
This project is based on a collaboration between the team of Prof. Yannick Landais at the ISM and the team of Prof. Henri Cramail at LCPO, a long-lasting and fruitful partnership. Very innovative methods for the greener synthesis of urethanes mediated by visible-light have been recently described by this consortium .
Building on this expertise, the role of the Ph.D. candidate will be to develop new methods for the synthesis of polyurethanes using light stimuli. He or she will have the opportunity to work at the interface of photo-chemistry and polymer chemistry. The first part of this multidisciplinary project will be devoted to the development of a photocatalytic system adapted to the synthesis of thermoplastic as well as thermosetting polyurethanes. Ultimately, the candidate will explore the potential of this chemistry in applications including foaming and lithography (2D and 3D) technologies.

This project is a collaboration between the team of Prof. Henri Cramail at LCPO (Bordeaux, expertise in polymer chemistry) and the team of Prof. Yannick Landais at the ISM (Bordeaux, expertise in photo-catalysis).
The essential of the work of the Ph.D. candidates will be devoted to the photo-activated synthesis of polymers and will thus be carried out at LCPO, but a close collaboration with ISM is expected. Several missions will be programmed at the ISM, just a few blocks away from the LCPO.
The Laboratory of Chemistry of Organic Polymers (LCPO) is a joint research unit affiliated to the CNRS, the University of Bordeaux and l'Institut Polytechnique de Bordeaux (http://www.lcpo.fr). The LCPO is organized into 4 research teams with a total strength of nearly 150 people, including about 50 permanent staff.
With over 30 years of expertise in polymer chemistry, researches at LCPO aim at:
- developing innovative methodologies for precision synthesis of polymers, using in particular biomimetic and/or green chemistry pathways
- designing functional polymer materials by macromolecular engineering and self-assembly.
The work of the recruited Ph.D. will be carried out in team 2 of the LCPO and in collaboration.
Team 2 is entitled "Biopolymers and Bio-sourced Polymers" and is headed by Henri Cramail.
The team is developing the use of bio-resources for polymer synthesis with the following main orientations:
- the use of (modified) vegetable oils as monomers
- obtaining polymerizable synthons from ligno-cellulosic biomass
This project will be carried out within Team 2. In this context, an important aspect of the work will be to respect the principles of green chemistry (as much as possible) and to use chemicals and synthons stemming from bioresources. The project will be supervised by Henri Cramail (Professor at the University of Bordeaux) and Thomas Vidil (CNRS researcher at the LCPO)
The scientific production will be valorized through patents and publications in high impact journals.
