STERHEO - RVB NoirSTERHEO

Structure and rheology of polymers, processes and modelling

The STeRHEO division aims to unravel the interactions between the formulation of polymer materials, their structuring in the shaping processes and their performance properties. This involves identifying the process’s guiding mechanisms, translating them into experiments conducive to a fundamental scientific approach and the development of relevant models. STeRHEO brings together theoretical and experimental skills in several areas, including:

Rheology of polymer systems

Transient regime, non-linear viscoelasticity (shear and elongation), structuring kinetics, percolation and anisotropy generation

Processes

Reactive extrusion: load generation, compatibilization Co-extrusion, blending, interface dynamics 3D printing, spinning, bi-injection moulding, rotational moulding, thermoforming, etc.

Physics of soft materials

Modelling of scalable systems, emulsions, soft colloids, nanocomposites, etc.

Associated spectroscopic techniques

Radiation diffusions (RX, light, neutrons) Couplings: Rheology / Radiation, Rheology / Conductivity
