The t of oil droplets (Fig. 3b) show initially a similar variationwith a slight increase at 0.5% w/w followed by a decrease of t (<7◦)reported for surfaces corresponding to 1, 2 and 3% w/w. However,at 4% w/w an increase of t (=14.2◦) for the oil droplets is observedwhich is pronounced at 5% w/w where oil droplets are pinned andcan roll off the surface only when this is turned by almost 90◦. Thisincrease of t is accompanied by a decrease of s (Fig. 3b).
