| 제목 | Bio-inspired Design and Fabrication of Superhydrophobic Surfaces for Full-range Water Droplet Manipulation |
| 초록 | Nature abounds with mysterious biological creatures and organisms that exhibit unique surface wettability, such as lotus leaves with self-cleaning property, rice leaves and butterfly wings with directional adhesion property, mosquito eyes with anti-fogging functionality, and the Namib desert beetle and spider silk with water collection ability. These special wetting properties and corresponding integrated functions have been received great attention, and biomimicking these fascinating surfaces has been one of the most active research topics in the past few years. Among the efforts to obtain artificially fabricated multifunctional smart surfaces inspired in nature, superhydrophobic surfaces with extremely water repellent properties have received considerable attention as they have various potential applications, including self-cleaning fabrics, anti-fog windows, drag reduction, and water transportation. In particular, surface wettability and water adhesion control of artificial superhydrophobic surfaces are crucial in advanced potential applications, such as open channel microfluidic based sensors, highly efficient biomolecule analysis, and dynamic solubility control of nanoparticles. In this dissertation, we introduced the novel and facile methods to obtain bio-inspired superhydrophobic surface with various functions, such as water adhesive, water repellent, water collecting and guiding. In addition, we demonstrated the new superhydrophobic surface with switchable and controllable wetting property, which cannot be observed in nature, via simple surface modifications of substrate for the full-range water manipulations. We also highlighted the newer and emerging lab-on-a-chip application, stem cell spheroids formation, using the smart bio-inspired superhydrophobic surface. |
