DEFI - RVB NoirDEFI

Polymers for the development of materials with a low environmental impact

The interdisciplinary DEFI division aims to coordinate the Unit’s complementary skills for the eco-design of more environmentally-friendly materials, materials used in the field of clean and renewable energies or responding to the issue of reducing CO2 emissions.

The division’s activity focuses on three major areas:

Polymers for a preserved environment

  • DEFI1MOD-2_88x351Derived from renewable resources
  • Biodegradable polymers used for short-lived applications
  • Polymers designed for performance and sustainability, but recyclable mechanically or chemically

Polymers for clean energies

  • Composites for wind power
  • Flexible polymers for photovoltaics
  • Conductive polymers for energy recovery sensors
  • Polymer materials for energy storage

Polymers for resource preservation

  • Lightening (d>0.5) by composites or low porosity polymers
  • For structural parts in the transport industry
  • Foaming (d>0.1) for architectural thermal insulation Alternative to Multi-layer Materials Multi-material
  • Clean processes (in supercritical CO2, reactive extrusion, microwave heated or plastified by “green” ionic liquids)
