Abstract

Maxwell displacement current(MDC) measuring technique has been employed to study the dielectric property of Langmuir-films. A method for determining the dielectric relaxation time ${\tau}$ of floating monolayers on the water surface is presented. MDC flowing across monolayers is analyzed using a rod-like molecular model. It is revealed that the dielectric relaxation time ${\tau}$ of monolayers in the isotropic polar orientational phase is determined using a liner relationship between the monolayer compression speed ${\alpha}$ and the molecular area Am. Compression speed ${\alpha}$ was about 30, 40, 50mm/min.
