Abstract
- Optical sensors having transparent windows act as the eyes in marine exploration. However, biofouling is a critical problem to blind them. In this report, transparent glass is used as the substrate to grow robust SiO 2 onto the surface via a facile breath figure approach under the temperature of 40 °C. After grafting of long-chain organic molecule, a hydrophobic surface is obtained. The three-dimensional interconnecting net configuration acts as the reservoir for accommodating the lubricant to form the liquid-infused surface. After lubrication with oil phase, SiO 2 performs as the transparent medium for light to transmit. Taking diatom as the representative organism, the surface can effectively inhibit biofouling growth. Time-dependent fluorescent images are used to trace the inhibition effect of the liquid-infused surface. Even immersed in seawater for 11 days, the inhibition efficiency can still maintain 96.1%.
