Abstract: | The structural features of a thin polar liquid film in an electric field of a charged substrate have been theoretically investigated
using methods of statistical physics. It has been established that electrical interactions in this system lead to a change
in the structure of the polar liquid and to the formation of clusters in it. A self-consistent nonlinear equation has been
derived for describing the distribution of the potential and strength of the electric field inside the film under investigation.
The depth of penetration of this field into the liquid medium has been studied as a function of the electrical activity of
the substrate, temperature, degree of polarity of the liquid, and concentration of interface heterocharges. It has been revealed
that the extent of structured regions in the liquid increases with an increase in the potential gradient of the internal field
and with a decrease in the temperature. |
