Figure 5. Hexadecane-oleic acid /water/glass wetting cycle with hybrid-wetting behavior.

The wetting behavior of liquid/liquid/solid systems is not only dependent on the two liquid phases, but upon the interaction of the solid surface with these liquids (see Equation 1). An example is in the wetting cycles for glass and PTFE in a hexadecane/water system. 

A wetting cycle for a glass slide in a hexadecane/water system has the typical water-wetting cycle shown previously in Figure 3.
