In chemistry and physics, cohesion, also called cohesive attraction or cohesive force, is the action or property of like molecules sticking together, being mutually attractive. It is an intrinsic prop

Wetting is the ability of a liquid to maintain contact with a solid surface by displacing another substance or material – either a gas, or other liquid not miscible with the wetting liquid – due to th
Water bead on a fabric that has been made non-wetting by chemical treatment.

Strands of an uncharged ferrocene-substituted polymer are tethered to a hydrophobic silica surface. Oxidation of the ferrocenyl groups produces a hydrophilic surface due to electrostatic attractions between the resulting charges and the polar solvent.
