Tailored 3D-printed viscoelastic adsorbents for efficient removal of micro- and nanoplastics in water

Le résumé fourni par la source

Micro- and nanoplastics (MNPs) are an emerging environmental threat that demands efficient removal strategies. This study introduces a viscoelastic 3D adsorbent that combines viscoelastic adhesives with 3D-printed scaffolds to enable rapid and effective MNP capture. The adsorbent exploits both van der Waals and electrostatic interactions to achieve fast and irreversible adsorption in diverse aquatic environments. Its viscoelastic properties are optimized to selectively adsorb microplastics through physical adhesion and nanoplastics via electrostatic attraction. The 3D-printed scaffold design maximizes surface area and adsorption efficiency. Experimental results show that the adsorbent removes over 99% of MNPs within minutes, maintaining high performance across various water conditions and plastic types. Simple solvent treatment restores adsorption capacity for repeated use. The customizable nature of 3D printing enhances scalability for water purification and environmental remediation. This versatile and sustainable approach offers a pathway to large-scale treatment of MNP pollution while enabling long-term efficiency and reusability in practical applications.
