Web16 jun. 2024 · A hydrophilic surface has a contact angle (θ) <90° while the hydrophobic surface exhibit a contact angle (θ) >90°, shown in Figure 1 (below). A higher contact angle indicates the stronger liquid-liquid interaction rather than liquid-surface interaction thus making the material hydrophobic. Web17 aug. 2024 · The degree of surface hydrophilicity (or -phobicity) can be determined by the contact angle measurement. The surface is said to be hydrophilic if the contact angle is below 90 degrees. If the contact angle is lower than 5 degrees the surface is completely wetted and called superhydrophilic.

Web14 mei 2024 · Through dynamic water contact angle (WCA) measurements, we show the PDMS-PEG copolymer segregates to the surface when exposed to water/aqueous solutions, which renders the surface more hydrophilic ...

WebAnother possibility is piranha or RCA cleaning procedures; mixes of hydrogen peroxide and sulfuric acid or ammonia respectively.
