Hysteresis of Isotherms of Mixed Monolayers of N-Octadecyl-N′-phenylthiourea and Stearic Acid at Air/Water Interface

Figure 2

Surface pressure area hysteresis isotherms of premixed OPT/SA monolayers of approximately equimolar composition at 25°C. Recompression of the monolayer after the first compression and expansion does not retrace the first cycle. The second and subsequent cycles, however, coincide.
