Tailoring Interactions of Random Copolymer Polyelectrolyte Complexes to Remove Nanoplastic Contaminants from Water
Summary
Researchers developed oppositely charged random copolymer polyelectrolyte complexes and demonstrated their ability to quantitatively remove nanoplastic contamination from aqueous solution, finding through computational simulations and quartz crystal microbalance experiments that hydrophobic nanostructures play a central role in the remediation mechanism.
We investigate the usage of polyelectrolyte complex materials for water remediation purposes, specifically their ability to remove nanoplastics from water, on which there is currently little to no prior research. We demonstrate that oppositely charged random copolymers are effective at quantitatively removing nanoplastic contamination from aqueous solution. The mechanisms underlying this remediation ability are explored through computational simulations, with corroborating quartz crystal microbalance adsorption experiments. We find that hydrophobic nanostructures and interactions likely play an important role.
