The current-voltage characteristics of sodium stearate thin films in an alternating electric field are investigated. The dynamics of the formation of space charge field created by hydrophobic chain mechanism and local destruction of the film with increasing voltage and time of self-destroyed the space charge region, are analyzed. The regularities of interaction between the fixed charges of the film formed by an anion-active sodium stearate with ion electrolytes are revealed.
