The viscoelastic properties of insoluble monolayers have been investigated by the excited electrocapillary waves method. Effective negative values of dilational viscosities have been obtained in the liquid expanded and liquid condensed phases of insoluble monolayers of myristic, pentadecanoic, and stearic acids. However, the surface viscosity remains… CONTINUE READING
