Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic. This property of water was important for the evolution of life. Hydrophobic interaction plays the most critical roles in the formation of the lipid bilayer of the cell membrane and the folding of proteins and nucleic acids; therefore, hydrophobic interaction is the foundation for the existence of life.
A self-assembled monolayer (SAM) is a layer of organic molecules formed spontaneously on a solid substrate. One end of the organic molecule binds to the solid surface via a covalent bond while the other end points outwards. Because the exposed end of the SAM determines the surface properties of the SAM modified substrate, we can alter a hydrophobic surface (a surface that expels water) into a hydrophilic surface (a surface that attracts water) by carefully selecting the SAM forming molecules

Thank you for the invitation,
I agree with the answer of Mr Mahmoud Shatnawi
hydrophile l'eau va passer contrairement hydrophobe n'absorbe pas de l'eau
la difference d'est l'absortion de l'eau
hydrophilic indicate water-lover and linked with componds contain water molecule
hydrophobic is hater- water molecule and don't react and solute with water
Hydrophilic molecules contain polar groups such as OH which can make hydrogen bond with the water molecule and dissolve or disperse in water while Hydrophobic molecule doet have and it is not miscible with water unles we use surfactants
hydrophilic as name indicate water loving contain water molecule
hydrophobic which hate water
