This three-year, $459,000 Project Grant from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) will fund research into the origins and mitigation of secondary microplastics and nanoplastics pollution. The grantee, Columbia University, will combine experimental and theoretical tools to elucidate the degradation mechanisms of semicrystalline polymers when exposed to mechanical forces, water, air and UV light. This work aims to delineate the critical physics underlying the formation of nanoplastics from these materials, which constitute over 70% of currently used plastics. In addition, the research proposes strategies such as copolymerization and material extrusion to increase connectivity between polymer crystals and thus mitigate nanoplastics creation. Broader impacts include undergraduate research opportunities, training of a diverse student cohort, and online learning modules related to nanoplastics for students. The award reflects the NSF's support for advancing scientific understanding and global sustainability.
