PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are a group of chemicals that is used in a wide range of industrial and consumer products. These chemicals are known for their resistance to heat, water, and oil, which makes them ideal for use in products such as non-stick cookware, food packaging, and stain-resistant clothing. However, the widespread use of PFAS has raised severe concerns about their potential health effects and environmental impacts. The other main concerns with PFAS is that they are extremely persistent in the environment. This has led to widespread contamination of soil, water, and air. This project ambitions an efficient extraction and removal of PFAS from contaminated water. It will rely on three main objectives: design and synthesis of (O1) new photoactive MOFs with an enhanced chemical stability and photoactivity under visible light, (O2) stimuli-responsive polymer-MOFs hybrid materials to enhance colloidal stability and extract MOF from water to finally (O3) study the PFAS removal performances under realistic conditions (with organic pollutants, ions…).
