제목 Inverted Hierarchical Structures for Multi-functional Optical Coatings
초록 Transparent substrates are widely used for optical applications from lenses for personal and sports eye-wares to transparent displays and sensors. While these surfaces require excellent optical properties, they often suffer from variety of environmental challenges such as excessive fogging and surface contamination. In this work, we demonstrate that a surface that simultaneously exhibits anti-fogging, anti-reflecting, and self-cleaning properties can be prepared by pattern transferring low surface energy microstructures onto a hetero-structured nanoscale thin film comprising of polymers and silica nanoparticles. The polymer/silica nanoparticle composite base layer serve as a hydrophilic reservoir, guiding the water molecules to preferably condense into and suppress reflection while the low surface energy microstructure enables the organic contaminant adsorbed on the surface to be easily removed by rinsing with water.
