Fluorinated Polyhedral Oligomeric Silsesquioxanes (F-POSS)
Abstract
Water-repellent materials, possessing a high degree of hydrophobicity are currently under a spotlight. Preparative approaches are often inspired by naturally evolved biological systems. Specifically, a leaf of the lotus plant exhibits an inherent self-cleaning mechanism resulting from micron-sized waxy nodes protruding from its surface such that water is naturally repelled, removing any foreign debris. This cleansing mechanism, commonly referred to as the "lotus effect," has been artificially reproduced in order to prepare materials with pronounced hydrophobicity. Utilized techniques include surface patterning, molecular self-assembly, deposition, and etching. However, these examples often require aggressive chemical surface treatments, high temperature post-surface modification, or elaborate patterning. For such reasons, there exists a demand to engineer hydrophobic materials that are easy to prepare on a large scale.
