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 large and growing family of polymers - 6th in the world, 18Mt / year. However, isocyanates are dangerous compounds which must be replaced by less dangerous compounds. The search for new isocyanate-free polyurethanes (NIPUs) is a major development axis for the vast majority of industries.
The objective of this research work is to identify access routes to bio-based binders, in particular polyurethanes without isocyanates for the development of 100% bio-based composites.
The work mainly concerns the synthesis of new biobased monomers, the study of their reactivity in polymerization and the study of the physico-chemical characteristics of the composites obtained. Finally, this work should give rise to the use of composite materials and the study of their application properties.
The candidate sought must have a doctorate in polymer chemistry. Strong skills in organic chemistry are also required.
The IAM team, based on organic chemistry applied to polymers, is recognized for its technological integration in the development of integrated solutions for the synthesis of materials, from monomers to polymers to meet high performance applications. For many years it has also developed chemistry using sober and clean processes and based on sustainable development (polymers from renewable resources, substitution, etc.). It is a team also recognized for its skills and expertise in the macromolecular chemistry of P and F heteroatoms.
