WebThe static contact angles could be an advancing angle, a receding angle, or any of multiple metastable angles between the two. Unless it is an advancing or receding angle it has no … WebA contact angle refers to the angle made between a solid/liquid/gas interface on a surface. One method of creating a three phase interface is by simply adding a droplet of fluid to a solid surface in air. This produces a measurable, surface-dependant angle as illustrated in …

The measuring condition (such as volume, boundary surface or solid surface) will not be changed anthropogenic when the drop (or bubble for captive bubble method) is placed on solid surface. WebJun 8, 2024 · Although static water contact angle measurement can be used to determine hydrophilicity or -phobicity of the surface, it might not always be enough. As the static contact angle can take any value in between the advancing and receding values, there can be a big variation in your static contact angle data from sample to sample. narrow shard
