The objective of this research is to identify access routes to bio-based binders, in particular polyurethanes without isocyanates for the production of 100% biobased composites.
The work focuses on the synthesis of new biosourced monomers, the study of their reactivity in polymerization and the study of the physicochemical characteristics of the composites obtained. Finally, this work must lead to the implementation of composite materials and the study of their application properties.
The cork powder, purified with supercritical CO2, is formulated with a polymeric binder to obtain technological shutters, suitable for food contact. The current binder is a polyurethane obtained by reacting a polyol with a diisocyanate. Polyurethanes (PUs) represent a very important family of polymers and in full development - 6th world rank, 18Mt / year. However, isocyanates are dangerous compounds that must be substituted with less dangerous compounds. Thus the search for new polyurethanes without isocyanates (NIPUs) is a major development axis for a large majority of industries.
The candidate will be required to have a doctorate in polymer chemistry. Solid skills in organic chemistry are also required.
The IAM team, based on organic chemistry applied to polymers, is recognized for its technological integration into the development of integrated materials synthesis solutions, from monomers to polymers to meet high performance applications. For many years, it has also developed a chemistry using simple and clean processes and based on sustainable development (polymers derived from renewable resources, substitution ...). It is also recognized for its expertise and expertise in the macromolecular chemistry of P and F heteroatoms.
