Fluodamage: an ERC-POC project at ESPCI

The ERC-POC FLUODAMAGE project of Costantino Creton, CNRS Research Director at the SIMM laboratoryand Dean of Research at ESPCI Paris, has just been selected among the 76 winning projects of the third ERC Proof of Concept call. A first step to help researchers to test the potential applications of their discovery. FLUODAMAGE is a project to study materials close to rupture, using molecular markers and non-invasive optical imaging techniques.

When the material is broken, a fluorescence phenomenon is observed, linked to chemical bond scission at certain locations in the material (in the presence of molecular markers). © Juliette Slootman (recent doctoral thesis on this subject) Fluorescent molecules to detect weaknesses in a material.

Costantino Creton’s team has developed an experiment that relies on the incorporation of fluorescent molecules to track how certain materials fail due to mechanical stress.
"Our laboratory experiments work fairly well with model systems, but we know that industrial problems are more complex," says Creton. For industrialists, it is above all a question of service life: how can we predict the service life of a soft material (rubber, tyre, sealant or adhesive), without beaking it?

The SIMM laboratory team hopes to be able to detect a low level of damage by non-destructive testing. The project, which is expected to last 18 months, is also funded with 150,000 euros. The researchers will be able to develop a longer test and verify their hypothesis in conditions close to actual use.
"This is very good news, we are going to be able to take our tests further thanks to this original call for projects, for the preparation of which the CNRS Innovation team has been of invaluable assistance"
