Changes of contact angle and drop radius R d before and after the C–W transition of droplets during evaporation. Experimental data originate from literature,[ 13 ] θ I = 109°, θ A = 109°; (a) d = 5 μm, H = 10 μm; (b) d = 14 μm, H = 30 μm. Here the droplet volume required in the model calculation is solved by using the measured droplet radius and the contact angle.
