Missions

The aim of this project is to develop new routes for the synthesis of ionic liquids (IL) and ionic liquid cristals (ILC) starting from biosourced synthons. One of the main objective of this work will be to conceive efficient synthesis routes that meet the expectations of green chemistry. The thermomechanical properties of the resulting ILs and ILCs will be fully characterized as well as the self-organisation of the ILCs at the molecular level (mesophases). A second challenge will be to tailor the synthesis routes to obtain polymerizable ILs and ILCs. Polymers of ILs and ILCs (PILs and PILCs) will then be obtained by using conventional methods of controlled radical polymerization. Block copolymers of PILs and PILCs will be synthesized as well, notably by incorporating blocks of common polymers like polystyrene. After a thorough characterization of these polymers, another dimension of the project will be to valorize their use in high value added applications like conductive materials.

Activities

- Synthesis of ionic liquids (ILs) and ionic liquid cristals (ILCs) starting from bioresouces
- Synthesis of homopolymers and block copolymers using polymerizable ILs and ILCs
- Molecular characterization of the ILs and ILCs as well as their polymeric counterparts (RMN, UV, IR, SEC…)
- Characterization of the self-organization of the ILCs at the molecular scale (DSC, rheology, optical microscopy, X Ray)
- Characterization of the thermomechanical properties of the polymers of ILs and ILCs (DSC, DMA, rheology, tensile testing…)
- Characterization of the potential nanostructure of the polymers of ILs and ILCs (rheology, electronic microscopy, X ray)
- Writing of reports, publications and patents

Skills

Mandatory :
- Molecular and macromolecular synthesis
- Common methods for the characterization of the molecular properties of polymers

Appreciated:
- Common methods for the characterization of the thermomechanical properties of polymers
- First experience with ionic liquids and/or liquid cristals

Work Context

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.
