Abstract(in English) | Dielectric relaxation phenomena of 4-cyano-4'-5-alkyl-biphenyl (5CB) monolayer at the air-water interface have been investigated. Maxwell displacement current (MDC;I)-area per molecule (:A) isotherms and surface pressure (:π)-A isotherms were measured at several monolayer compression ratios. Dipole moment (:m_Z) -A isotherm and dm_Z/dt-A isotherm were evaluated from I-A isotherm. It was found that in the range (range 2) where the surface pressure is almost zero, m_Z tends to increase at wide A as the compression ratio becomes small, whereas m_Z-A isotherm coincides each other for various compression ratios in the range where the surface pressure increases by monolayer compression. These results indicate that the compression process of 5CB monolayer in the range 2 is a non-equilibrium process. Relaxation time (:τ)-A isotherm and dipole moment at equilibrium state (:m_ |
