This award supports Professor Lauren Pincus at George Washington University to develop a predictive understanding of plastic (polyethylene, polystyrene, and polyethylene terephthalate) photo-oxidation rates and pathways. Photo-oxidative degradation of plastics involves a complex series of reactions initiated by UV-generated free radicals, which could result in molecular changes in plastic structure and surface…
