Objectives
• To develop long-lasting self-cleaning superhydrophobic surfaces in the Cassie-Baxter state, and inhibit the Cassie-to-Wenzel state transition by exploiting photothermal effects from the nanostructures and nanomaterials.• To promote the slippage of viscous droplets and mucus on superhydrophobic surfaces by using magnetic cilia-mimicking nanopillars to reduce the sticky droplet attachment.• To deploy nanoparticles on the superhydrophobic surfaces to disinfect any remaining viruses, and to verify the antiviral performance of the new superhydrophobic surfaces by testing them against SARS-CoV-2 and other respiratory infectious viruses.• To develop a roll-to-roll integrated manufacturing system for scalable fabrication of long-lasting, highly-efficient, and low-cost self-cleaning antiviral surfaces.
