Non-Equilibrium Phase-Separated State of (Palmitic Acid/Lignoceric Acid) Mixed Monolayer.

The effect of solvent species and quantity of solvent used for spreading on the morphology of Langmuir monolayer composed of palmitic and lignoceric acids was investigated based on atomic force microscopy observations. The variation in domain size depending on the evaporation time of the spreading solution indicated that the mixed monolayer was in a non-equilibrium phase-separated state. [ABSTRACT FROM AUTHOR]
