Several factors can influence the contact angle on a catalytic surface:
Surface Roughness: Increased roughness generally enhances hydrophilicity or hydrophobicity, depending on the intrinsic properties of the material. Surface Chemistry: The presence of specific functional groups can alter the surface energy and, consequently, the contact angle. Temperature: Higher temperatures can change the surface tension of the liquid, affecting the contact angle. Atmospheric Conditions: Humidity and the presence of contaminants can also impact the contact angle measurements.
