Hydrophobic materials can be created using two methods. The simpler method is to coat a surface with wax, oil, or grease. The other is using nanoengineering to help create a unique, nanopatterned textured surface.
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 materials are known as non-polar materials with a low affinity to water, which makes them water repelling. A contact angle of less than 90° indicates hydrophilic interaction where as an angle greater than 90° indicates a hydrophobic interaction.
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.

Any object coated with our NeverWet® super hydrophobic coating literally cannot be touched by liquid. Any liquid placed on the super hydrophobic coating is repelled and simply rolls off without touching the underlying surface. Not only is this amazing to see, but it solves a myriad of problems.

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.
