The aim of this project is to develop in collaboration with ArianeGroup SAS, new crosslinked materials and that can be used under severe temperature conditions and in an oxidizing environment. The first objective of the work will be to synthesize epoxidized biobased such as polyepoxides. The study of the formulation of these monomers will be carried out with hardeners of different chemical nature. A second component will be dedicated to the characterization of the physicochemical properties of these polymers and related composite materials. A third aspect of the work will be to verify the possibility to scale-up the synthesis of the monomers and polymers.
- Synthesis of monomers and polymers with very well controlled architectures
- Characterization of the molecular properties of the polymers according to the usual methodologies (SEC, NMR, UV, IR)
- Characterization of the thermomechanical properties of the polymers according to the usual methodologies (DSC, DMA, rheology, tensile test, etc.)
- Establish the structure-property relationship of the materials between the architecture of the polymers and their thermomechanical as well as adhesive and permeation properties.
- Scale-up of the synthesis of the polymer
- 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
The Laboratory of Chemistry of Organic Polymers (LCPO) is a joint research unit affiliated to the CNRS, the University of Bordeaux and the 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, in the fields of renewable materials, health and energy
- establishing strong links with the socio-economy world.
The work of the recruited agent will be carried out in team 2 of the LCPO in collaboration with an industrial partner.
Team 2, entitled "Biopolymers and Bio-sourced Polymers", is headed by Henri Cramail.
The team explores green routes to valorize the bio-resources for the design of sustainable polymer materials, with the following main orientations:
- the depolymerization of ligno-cellulosic biomass and the valorization of the products so-formed (oligo-lignin, phenols, saccharinic acids, oligosaccharides)
- the synthesis of bio-based monomers, mainly from lipids, and the investigation of their polymerization (polyesters, non isocyanate polyurethanes, polyamides, epoxy networks)
- the chemical modification of polysaccharides, essentially cellulose and chitosane, for the design of functional polymer materials.
