WebIt should be stated here that hydrophobicity and hydrophilicity are terms, which are used here to describe a macroscopic phenomenon but are in part related to the nature of molecular functionalities (non-polar or polar, respectively). However, the contact angle of liquids on solids is not limited to water alone. WebHydrophobicity is frequently associated with oleophilicity (the affinity of a substance for oils) since nonpolar organic substitution is often hydrocarbon in nature and shares structural similarities with many oils. The hydrophobic and oleophilic effect …
WebSmart responsive surfaces switching reversibly between super-hydrophobicity and super-hydrophilicity can be effectively fabricated by modification of stimuli-responsive materials on rough surfaces. The externally applied stimuli include light irradiation, electrical potential, temperature, pH or selected solvents, and mechanical forces.
