摘要：

The formation process of sodium lauryl sulfate monolayers on the surface of octadecanethiol self-assembled monolayers was investigated by the method of cyclic voltammetry and ac impedance spectroscopy. The pinhole in an octadecanethiol-coated gold electrode can be patched when adding sodium lauryl sulfate to solution. The charge transfer resistance increased but the membrane capacitance decreased with the addition of sodium lauryl sulfate or other amphiphilic substance, indicating that the adsorption of sodium lauryl sulfate on the electrode surface from solution.
