Summary

UV irradiation was found to increase the aggregation of polystyrene nanoplastics to varying degrees depending on surface functional groups and electrolyte conditions, with free radicals playing a key role. Understanding aggregation behavior is important for predicting how nanoplastics behave and settle in aquatic environments.

Polymers

UV irradiation increased the aggregation of polystyrene nanoplastics to different extents depending on the surface functional groups and electrolyte species.
