VOLTAMMETRIC METHOD AS A TOOL IN DETECTING SURFACTANT-INDUCED DISRUPTION OF A LANGMUIR-BLODGETT FILM

Abstract

The interaction of surfactants with a stearic acid LB membrane on a glassy-carbon electrode is shown to be conveniently evaluated by cyclic voltammetry. The membrane disrupting effect of surfactants depended on their structure : the length of hydrophobic carbon chain and the charge of hydrophilic group.
