Rheology
Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Content
Many materials around us (such as food, gels, polymer melts, ...) behave as viscoelastic materials, and their flow properties depend on many parameters such as the time, the strain applied, or the temperature.
The main objective of LMECA2141 is to look at these materials and try to understand how their viscoelastic properties depends on their composition. The lectures will focus on:
1. Properties of viscoelastic materials
2. Rheometry
3. Flow properties of a polymer in solution
4. Flow properties of  polymer melt: the linear chains
5. Flow properties of  polymer melts: Branched polymers
6. Flow properties of  polymer melts: Influence of the sample composition
7. Viscoelastic response of a polymer melts under large deformation
8. Viscoelastic properties of gels and reversible polymer network
9. Viscoelastic properties of colloidal particles: hard spheres
10. Viscoelastic properties of colloidal particles: soft colloids
Evaluation methods
