TL;DR: In this paper, it is shown that the controversy with respect to measurement and interpretation of contact angles is due to the fact that some (or all) of the assumptions made in all energetic approaches are violated when contact angles are measured and processed.

Contact angles and their temperature dependence: thermodynamic status, measurement, interpretation and application
TL;DR: In this paper, the vertical plate model is used to measure contact angles on smooth and heterogeneous rolid surfaces and their temperature dependence. But the model is not suitable for smooth and homogeneous surfaces.

Techniques of Measuring Contact Angles
A. W. Neumann,Robert J. Good +1 more
- 01 Jan 1979
TL;DR: In this paper, the authors investigated how the structure of a solid surface affects the contact angle that a liquid forms on the solid, and the level of structure considered there included features that are not macroscopically observed, such as microheterogeneities, or minute peaks, pits, hills, and grooves.

Contact angles on hydrophobic solid surfaces and their interpretation
Dongqing Li,A. W. Neumann +1 more
TL;DR: In this article, contact angles of 17 liquids on 3 hydrophobic solid surfaces, FC721, fluorinated ethylene propylene, and polyethylene terephthalate, were measured by using the Axisymmetric Drop Shape Analysis-Profile (ADSA-P) technique.

The spreading of liquids on low-energy surfaces. III. Hydrocarbon surfaces
H.W Fox,William A Zisman +1 more
TL;DR: In this article, it was shown that the methyl-rich surfaces of C36 and paraffin are not wetted by a wide variety of organic liquids, including the n-alkanes, so that the rule that nonpolar solids are not wettable by non-polar liquids is again found to be erroneous.

- 15 Mar 1989
TL;DR: In this paper, the existence of negative interfacial tension at liquid/liquid interfaces was shown to be a real phenomenon between monopolar surfaces (i.e., surfaces with mainly H-acceptor properties) and polar liquids.
