Water Contact Angles on Poly(ethylene terephthalate) Film Exposed to Atmospheric Pressure Plasma
TLDR
In this article, the authors examined the contact angle hysteresis on the poly(ethylene terephthalate), PET, film was exposed to atmospheric pressure plasma under various plasma processing parameters.Abstract:
The poly(ethylene terephthalate), PET, film was exposed to atmospheric pressure plasma under various plasma processing parameters. The wettability of the PET film immediately after the exposure and after storage in air, which was determined by the sessile drop method, was strongly dependent on the plasma processing parameters. The contact angle hysteresis on the plasma-exposed PET film was examined by the Wilhelmy method. It was found that the hydrophobic recovery of the PET surface on storage after the plasma exposure was observed only for the advancing contact angle and that the receding angle remained almost the same. These experimental findings were explained on the basis of the calculation by Johnson and Dettre for the advancing and receding contact angles on model heterogeneous surfaces.read more

The Cassie equation: how it is meant to be used.
TL;DR: It is shown that for surfaces wet with a composite interface, the commonly used form of the Cassie-Baxter equation, cosθ(c)=f(1)cosθ-(1-f), is only correct for the case of flat topped pillar geometry without any penetration of the liquid.
