A given system of strong, liquid, and vape e-liquids vapor at a given temperature and strain has a singular equilibrium contact angle. The equilibrium contact angle reflects the relative power of the liquid, solid, and vapour molecular interaction. Static measurements yield values in-between the advancing and receding contact angle relying on deposition parameters (e.g. velocity, angle, and drop measurement) and vape e-liquids drop history (e.g. evaporation from time of deposition).
At a given surface tilt angle, the advancing and receding contact angles shall be met and the drop will transfer on the surface. As the tilt angle increases the contact angles will proceed to change but the contact space between the drop and surface will remain fixed. Based on this strategy, if the energetic compensation is less favorable than the defect value in bulk water-estimated round −6 kJ/mol, known as the Defect Interaction Threshold (DIT)-the system exhibits hydrophobic behavior, in step with contact angles exceeding 90°.
This provides a non-arbitrary molecular basis for the macroscopic contact angle criterion and complements classical Young-Dupré interpretations.
A current molecular energetic perspective explains the classical 90° threshold by quantifying the power of a system to compensate for hydrogen-bond defects it induces in its hydration layer.
