Carnot PolyNat

PolyNat Carnot Institute is devoted to the design of new biosourced functional and innovative materials and devices. Our strategy is built around four scientific and technological challenges: extraction/valorisation and functionalisation of biosourced building blocks, controlled self-assembly and nano-organisation, manufacturing and development processes. Our research combines experimental and modelling / simulation approaches from the proof of concept to the production at a pilot scale.

Eco-conception and eco-production of high-added value innovative and functional materials and devices.


Towards an innovative green carbohydrates engineering…  

PolyNat focuses its partnership-based research on:

  • Biosourced building blocks extraction / valorisation: molecules (oligosaccharides, aromatic compounds), biopolymers (hemicelluloses, lignins, cellulose), nanocellulose (nanocrystals, microfi brils, nanofi brils), fi bres and lignocellulosic particles.
  • Building blocks and materials functionalization for targeted properties: chemical, enzymatic and/or physical modifi cations.
  • Controlled self-assembly and nano-organisation: smart surfaces, three-dimensional assembly and functionalized glyconanoparticles (targeting and controlled release).
  • Production and development processes of biosourced materials: interactions at interfaces and device miniaturization.

PolyNat research strategy relies on:

  • An integrated approach from the laboratory proof of concept to the pilot scale.
  • Modelling, simulation and characterisation based on multi-scale approaches and physical-chemical coupling analysis.

PolyNat Industries Forum, an international impact


We aim to reinforce the links between research and industry beyond our borders in the fi eld of biosourced materials.
