Any of the standard methyl terminated straight chain alkanethiols will produce a hydrophobic surface. These thiols assemble into close packed layers leaving mainly the terminal methyl group exposed to the surface. Methyl terminated alkanethiols with chain lengths of 9 carbons or more typically have contact angles greater than 110 degrees when assembled for at least 24 hours.
