The LGP2, laboratory of Grenoble INP-Pagora, is a member of PolyNat, dedicated to the eco-production of high-added-value functional biosourced materials. PolyNat obtained the Carnot Label of Excellence at the end of April 2011 for the period 2011-2015.
Five Grenoble research centers will develop a research partnership together with world economic leaders: Centre de Recherches sur les Macromolécules Végétales (Cermav), LGP2, Centre Technique du Papier (CTP), Laboratoire de Rhéologie & Procédés, and Laboratoire Sols, Solides, Structures, Risques (3S-R).

 PolyNat, dedicated to the eco-production of high-added-value functional biosourced materials

More information

Carnot PolyNat's goal is to further develop the knowledge of natural glycopolymers and the organization of fiber to the nano and microscopic scale as well as the understanding the property structure relations on different levels.

Relying on cutting edge research, it aims at developing functional biosourced materials, from the laboratory to the industrial production through a two-stage process:




  To first create materials, called hybrids, resulting from the auto-assembly of elementary bricks that constitute plant matter – glycopolymers, nano-crystals, cellulosic fibers – modified or not with components coming from fossil resources.
  To create in the long term 100% biosourced materials.  

This strategy will allow the progressive switch from fossil carbon to renewable carbon by facilitating a faster integration into industrial sectors and innovative applications.

The Carnot PolyNat Institute shall draw on the scientific expertise of the five partner laboratories in the fields of physico-chemistry and suspension rheology, chemistry and physico-chemistry of polymers and colloids, multiphasic fluid mechanics, paper and cardboard production processes and the shaping of composite materials.

Five scientific and technological challenges are to be met:

  To exploit raw material heterogeneity at the nano and microscopic scale.
  To master the auto-assembly and the nano-organization of natural glycopolymers in view of high-added-value applications  
    To master nano-crystal and cellulose microfibril properties  
    To master and convert biosourced product properties in order to obtain the targeted functionalities  
    Eco-processes, from the elaboration of material to the industrial process: validation of the industrial concept to the pilot scale (gros volume et grande surface)  

The functionalization of fibers and natural glycoplymers will give the new materials varied properties adapted to specific needs: memory effect, conductivity, data storage, optical properties, barrier properties, mechanical properties, thermoformability, thermal properties,...

These functional biosourced materials will replace the existing materials on mass and niche markets, and will also allow new markets to be created using properties that up until now were impossible to use on the industrial level.

These varied properties will meet technological challenges in numerous fields:

  Short term: packaging, pulp industries, paper and cardboard (smart paper), printing (functional inks), health (medical material, smart patches and implants), construction (insulation).
  Mid-term: data security, health (interactive hydrogels, glycochips), nano-electronics, displays (very large conformable screens), plastics processing (new renewable materials), transport (light materials for the automotive industry), logistics (traceability, identification).  
    Long-term: sustainable electronic printing, biocaptors (nano-organized glycofilms) et food industries.
