Basic wettability tests of the samples with disk geometry constructed without using bonding materials. Distilled water droplet (in colour blue) and mineral oil droplet (in colour orange) contact angle measurement at times 0 and 10 s (after placing these droplets on the flat surface of the samples) of the samples with disk geometry D32, D33, D34, D35, D36 and D37.
