There are two common methods for measuring this range of contact angles.

For liquid moving quickly over a surface, the contact angle can be altered from its value at rest.

In other words, there is only one thermodynamically stable contact angle.

These groups believe that the apparent contact angle is largely dependent on the triple line.

This is because power capacities are based on the standard of a 180 contact angle.

At equilibrium, the contact angle of a liquid drop on a surface does not change.

The contact angle on a flat surface can be determined with a microscope.

The lower the contact angle, the higher the surface energy and more hydrophilic the material is.

You must have the contact angle as high as possible.

Choice of depends on which fluid the contact angle is specified for.
