Abstract

The efficient use of the Wilhelmy plate method to measure dynamic contact angles with asymmetric Au-thiol self-assembled monolayer (SAM) plates is studied. To prepare a Au(111) surface for SAM formation, gold is deposited only on one side of substrates. The sessile drop method is applied to estimate wettability of SAMs, because of this asymmetric feature of Au-thiol SAM samples. A modified Wilhelmy plate method to analyze the wettability of SAMs is proposed. Using mica as substrates, this method provides sufficient precision. This will help future studies of Au-thiol SAM wetting in combination with other surface characterization techniques.
