The National Science Foundation awarded Northwestern University a $455,075 Project Grant under the Mathematical and Physical Sciences federal grant program (CFDA 47.049) to develop recyclable thermoset polymers for high-performance composites. Over a three-year period ending May 2026, the university will synthesize model epoxy networks incorporating aromatic disulfide bonds at various points and use mechanical testing, Raman scattering, and thin film experiments to characterize the materials and understand deformation mechanisms. The goal is to establish a general strategy for producing tough, lightweight, recyclable polymers suitable for structural applications. Results from this research could help advance sustainable materials for electric vehicles, wind turbines, and other technologies that rely on strong, lightweight composites.
