(color online) Changes of base area and IFE barrier Eb plus wetting work of a droplet before and after its C–W translation during evaporation. Experimental data originate from literature.[7]d = 3 μm, p = 20 μm, H = 4.8 μm, θA = 116°. Note: the droplet volume required in model calculation was solved by using the measured droplet base area and receding contact angle.
