Langmuir-Blodgett film

A Langmuir-Blodgett film contains one or more monolayers of an organic material, deposited from the surface of a liquid onto a solid by immersing (or emersing) the solid substrate into (or from) the liquid. A monolayer is added with each immersion or emersion step, thus films with very accurate thickness can be formed. The monolayers are usually composed of polar molecules (see Chemical polarity) with a hydrophilic head and a hydrophobic tail (example: fatty acids).

Langmuir-Blodgett films are named after Irving Langmuir and Katharine B. Blodgett, who invented this technique. An alternative technique of creating single monolayers on surfaces is that of self-assembled monolayers.
