autophobicity

If adsorption equilibrium and mutual saturation of the phases is not achieved instantly, it is possible to distinguish the initial spreading tension, $σ i αβδ$ , from the final spreading tension, $σ f αβδ$ , when equilibrium has been reached. In the case in which $σ i αβδ$ is positive, while $σ f αβδ$ is negative, the system is said to exhibit autophobicity.
