摘要：
In the present communication, the monolayer characteristics of pyrene mixed with stearic acid (SA) at the air-water interface have been reported. The monolayer properties are investigated by recording and analyzing the surface pressure-area per molecule isotherm (pi-A) of the pyrene SA mixed films. It is observed that the pyrene and SA are miscible in the mixed monolayer. This miscibility/nonideality leads to phase separation between the constituent components (pyrene and SA). BAM image of the mixed monolayer confirms the miscibility or nonideal mixing at the mixed monolayer.
