Material Properties of Hydrophobic Materials A material’s surface can react either in a hydrophilic (water-loving) or a hydrophobic (water-hating) manner. To understand the behavior of a surface towards water, its contact angle (CA) has to be measured, which will provide information on the interaction energy between the surface and the liquid.
Water on hydrophobic surfaces will exhibit a high contact angle. Examples of hydrophobic molecules include the alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills, and chemical separation processes to remove non-polar substances from polar compounds.
Hydrophobic polymers are classified into sections based on chemical class and monomer functionality. Within each section, polymers are listed in alphabetical order, with copolymers placed in a section corresponding to the majority monomer in their compositions.

Fluoroalkylsilanes offer hydrophobicity as well as oleophobicity. Applications that call for these properties include: water-repellents, mineral ...

Hydrophilic materials have more thermodynamically favorable interactions with water and other polar solvents, such as ethanol, than they do with oil and non-polar solvents, such as cyclohexane. Molecular structures making them capable of hydrogen bonding is a primary contributor to the solubility of hydrophilic materials in polar solvents as ...
Hydrophobic surface is a surface that has the ability to repel water .The term hydrophobicity was derived from two Greek words that are hydro that means water and phobos that means fear; thus, hydrophobic surfaces can be define as material that tend to repel with water.
Hydrophobic and superhydrophobic materials have been successfully applied in many sectors, such as: (I) the removal of petroleum from aqueous solutions, (II) applied to plastic, ceramics, and mesh to contribute to the oil removal from aqueous solutions, (III) hydrophobic layers have a strong self-cleaning effect on plastics, heat pipes, metals ...
Examples of hydrophobic substances include fats, oils, waxes, alkanes and other greasy substances. The term hydrophobic comes from the Greek and is translated as “having a horror of water” or “water fearing.” In other words, hydrophobicity is a property of a substance that repels water.
