The wettability of thin films was evaluated with the use of the KRUSS DSA100 Drop Shape Analyzer. The tests were performed following the BS EN 828:2013 standard: 2 μL droplet of distilled water was spotted on the sample. The camera incline and magnification were set to +1 degree and 7x, respectively. The laboratory temperature was 23.5 °C, and the drop fit method was "tangent 1". The results are averages of ten measurements and the chosen data was written down after 3 s and 120 s.
