When aqueous solution was used as a probe liquid on the substrate where secondary forces like hydrogen bonding impart strong influence and resulting contact angle varies nonlinearly with the surface composition. They stated that, the Cassie equation is strictly applicable only when the intermolecular forces of interaction between probe liquid and the surface functionalities are dispersive. explored the effect of functionalized primary amines on oregano-soluble gold nanocrystals. These modifications are significant for heterogeneity factor even in small dimensions.

They proposed that, the Cassie equation needs modification to explain the impact of the surface free energy related with the three equilibrium interfacial tensions at contact line. examined the wetting properties of liquid profile at well-defined heterogeneous surfaces that were made up of hydrophilic and hydrophobic regions, synthesized by patterning self-assembled monolayers (SAMs). described that the advancing and receding water contact angle values on methylated quartz substrate change with the amount of trimethylsilane groups that were introduced, in a similar manner to that projected by the Cassie equation. Heterogeneity factor of a surface is unavoidable due to several reasons with one such prominent parameters connecting to the existence of impurities on the surface.
