The recruited post-doc will join the team “biopolymers and bio-sourced polymers” from the LCPO to develop new silicon materials that are physically crosslinked and remendable in a precise temperature range. The project will be carried out in collaboration with the ESPCI (Paris, Prof. Ludwik Leibler) and an industrial partner. The first objective of the work will be to synthesize silicon polymers with well controlled architectures. The thermo-mechanical properties of these polymers will then be fully characterized. A third aspect of the work will be to verify the possibility to scale-up the synthesis of the polymers. Beyond the industrial context, the project wants to address fundamental aspects of the physico-chemistry of polymers, notably the rationalization of the reactive compatibilization of highly incompatible polymers (e.g. PDMS and semi-crystallin polymers).
- Synthesis of PDMS copolymers with well controlled architectures
- Study of the molecular properties of the polymers according to the usual methodologies (SEC, NMR, UV, IR)
- Study of the thermomechanical properties of the polymers according to the usual methodologies (DSC, DMA, rheology, tensile test, etc.)
-Study of the nano-structuration of the material (if any) using diffusion of X-rays.
- Rationalize the structure-property relationship of the materials.
- Writing of reports, publications and patents
- Molecular and macromolecular synthesis
- Common methods for the characterization of the molecular properties of polymers
- Common methods for the characterization of the thermomechanical properties of polymers
- Reactive extrusion
This project is a collaboration between the LCPO (Bordeaux), the École Supérieur de Physique et de Chimie industrielle (Paris, Prof. Ludwik Leibler) and an industrial partner (confidential).
The essential of the work of the post-doc will be carried out in Bordeaux at 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 agent will be carried out in team 2 of the LCPO and in collaboration with an industrial partner.
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.
