WebApr 21, 2024 · The contact angle less than 90° signifies that solid surface is favorable for wetting, and if contact angle <10°, then the liquid will spread over the solid surface (as … WebDec 31, 2024 · The factor of wettability must be considered with regard to cleaning effectiveness. Wettability is measured by the contact angle of droplets. Hydrophilic surfaces allow droplets to spread wide, giving a low contact angle below 90°. On hydrophobic surfaces, droplets keep their shape with contact angles over 90° (Figure 3).
WebJul 1, 2012 · According to the literature, a contact angle below 90° indicates a good wetting surface for any liquid [33, [60] [61][62].
