Zinc Oxide Nanorods on Micropatterned Polymers Cut Marine Biofouling
Key Takeaways
- Sultan Qaboos University researchers coated three micropatterned polymers (D1, D2, D3) with zinc oxide nanorods.
- Coated surfaces became highly water-repellent, with contact angles of roughly 150-165 degrees versus 80-90 degrees uncoated.
- Bacterial attachment fell 60.3%, 48.8% and 5.8% on D1, D2 and D3; diatom coverage fell 9.9%, 72.9% and 71.8%.
- Effects are attributed to zinc ion release, reactive oxygen species, wettability and micro-nanoscale interactions.
