(color online) Changes of contact angle and IFE barrier Eb plus wetting work of sessile droplets before and after C–W translation on different textured surfaces. (a) experimental data originate from literature,[35]H = 10 μm when d = 5 μm, H = 30 μm when d = 14 μm; V = 5 μL, θI = 109°, θA = 109°; (b)–(d): experimental data originate from literature,[25]V = 3 μL, θI = 110°, θA = 116°, (b) d = 10 μm, H = 40 μm, (c) p = 50 μm, H = 20 μm, (d) H = 2 × d; (e) experimental data originate from literature,[16]V = 4.3 μL, θI = 107.5°, θA = 107.5°.
