Federal Project Grant Award Summary

Columbia University received a $500,000 Project Grant from the National Science Foundation's Division of Materials Research under the Mathematical and Physical Sciences program (CFDA 47.049) for the period July 1, 2026 through June 30, 2029. The award supports fundamental research on the formation mechanisms of micro and nanoplastics (MNPL), with focus on understanding how molecular-scale bond-breaking events in polymers—triggered by exposure to air, water, ultraviolet radiation, or physical stress—lead to the generation of larger plastic fragments. The research employs advanced analytical techniques including artificial intelligence and machine learning to identify connections between polymer structure, morphology (amorphous, semicrystalline, or rubber compositions), and ambient exposure conditions that facilitate MNPL formation. Research findings are intended to inform mitigation strategies and improve manufacturing practices for polymer-based materials.

In addition to core research deliverables, the award includes a significant educational outreach component. The principal investigator will develop educational modules in collaboration with K-12 teachers to illustrate MNPL formation mechanisms using everyday examples such as water agitation in plastic bottles, flow through polyvinyl chloride pipes, and tire wear. Building upon prior engagement with 17 New York City teachers, the project aims to enhance teacher education and create cascading effects across the K-12 education system regarding environmental impacts of polymer degradation and plastic pollution.
