Environmental fate

The ubiquitous presence and persistency of microplastics (MP) in aquatic environments are of particular concern since they constitute a potential threat to marine organisms and ecosystems. The objectives of our work are i) to detect and quantify MP in environmental samples (waters, sediment, biota); ii) to understand the patterns and the kinetics of polymer degradation in the aquatic environment and iii) to design model micro and nanoplastics in order to study their fate and interaction with aquatic life.

Smart polyurethanes were developed from various well defined heterofunctional oligomers obtained through a highly controlled oxidative or methatetic cleavage of unsaturated high molecular weight rubbers. These two methodologies  applicable from either natural source or waste rubber materials allow the access to new materials (antibacterial coatings, flame retardant foams, ionogels,etc…)
