Benjamin Franklin’s report to the British Royal Society in 1774 is a good starting point for the history of Langmuir or Langmuir-Blodgett films. In his report Franklin stated:
“At length at Clapham where there is, on the common, a large pond, which I observed to be one day very rough with the wind, …
Adhesion is the attraction between two dissimilar phases. Current theory divides adhesion into the three categories: fundamental adhesion, practical adhesion and thermodynamic adhesion.
Langmuir-Blodgett technology enables the deposition of single- or multimolecular layers from a liquid surface onto a solid substrate with excellent film structure control. LB is especially well suited for creating highly organized nanoparticle coatings, for example.

A Langmuir film can be defined as an insoluble spread monolayer of atoms or molecules floating at the liquid-gas interface (or liquid-liquid). Monolayer formation is possible due to the forces of self-assembly on insoluble molecules at the surface of a liquid.
Amphiphilic monolayers are the most …
