Structural properties of polymers and complex composites films

Several techniques mastered in the team allow deep polymer characterization providing structural and physical information.

Since both infrared and Raman spectroscopies give complementary information, we use these techniques as effective tools to monitor the molecular structure and properties of polymers. Coupled with chemometrics, vibrational spectroscopies are used in the team to control polymer structure under different environments (thermal degradation, UV ageing, mechanical deformation, very thin films behaviors); to develop new bio-based polymers (cellulose, natural rubber) and to assess the distribution of fillers in composite polymers.

We have also developed a strong expertise in X-ray reflectivity....
