Local surface pressure gradients observed during the transfer of mixed behenic acid/pentadecanoic acid Langmuir films

A mixed Langmuir film of behenic acid and pentadecanoic acid has been elaborated on water. This film contained domains and appeared very rigid and stable, but a vertical transfer onto a solid substrate was difficult because of this rigidity. A horizontal transfer technique was needed for efficiently transferring this film. The existence of pressure gradients in this film is discussed.
