Extreme Wetting-Resistant Multiscale Nano-/Microstructured Surfaces for Viscoelastic Liquid Repellence

Figure 3

Contact angles measurements of (a) water, (b) 35% latex, and (c) 60% latex on flat samples coated with FDTS-modified silica for varied reaction time and FDTS-silanol mole ratio, . Each inset represents an example of droplet shape (with highlighted edge line) for = 1 : 1 at day 3 of reaction. Note that the data points located at day 0 actually represent a reaction time of 15 min.
