Interrelationships between two-dimensional phase diagrams and mean molecular area-mole fraction curves in mixed monolayers

Abstract

Both two-dimensional phase diagrams and mean molecular area ( A)—mole fraction(x 2 π) curves have been investigated for various types of mixed monolayer systems. Two-dimensional phase diagram analysis and the behavior of A− x 2 π curves were found to be in good agreement with each other. From this result it was concluded that we should consider both phase diagrams and A− x 2 π curves of a mixed monolayer system in order to understand the behavior of the A− x 2 π curves.
