Static contact angle measurements with 3 µl of water. Five droplets per sample were analyzed on three samples each for both wetting states. Static contact angle (a) and volume (b) were measured 2 s, 60 s and 180 s after application. The reference data for normalization is “2 s”. For both wetting types a separate normalization was carried out. No significant differences were observed between the different measurement times suggesting stable measurement conditions.
