  2. Washburn's equation - Wikipedia

    en.wikipedia.org/wiki/Washburn's_equation

    Washburn's equation is also used commonly to determine the contact angle of a liquid to a powder using a force tensiometer. [ 5 ] In the case of porous materials, many issues have been raised both about the physical meaning of the calculated pore radius r {\displaystyle r} [ 6 ] and the real possibility to use this equation for the calculation ...

  4. Contact angle - Wikipedia

    en.wikipedia.org/wiki/Contact_angle

    Cloth, treated to be hydrophobic, shows a high contact angle. The theoretical description of contact angle arises from the consideration of a thermodynamic equilibrium between the three phases: the liquid phase (L), the solid phase (S), and the gas or vapor phase (G) (which could be a mixture of ambient atmosphere and an equilibrium concentration of the liquid vapor).

  5. Sessile drop technique - Wikipedia

    en.wikipedia.org/wiki/Sessile_drop_technique

    An alternative method for measuring the contact angle is the Wilhelmy method, which employs a sensitive force meter of some sort to measure a force that can be translated into a value of the contact angle. In this method, a small plate-shaped sample of the solid in question, attached to the arm of a force meter, is vertically dipped into a pool ...

  8. Captive bubble method - Wikipedia

    en.wikipedia.org/wiki/Captive_bubble_method

    The captive bubble method is a method for measuring the contact angle between a liquid and a solid, by using drop shape analysis. [1] In this method, a bubble of air is injected beneath a solid, the surface of which is located in the liquid, instead of placing a drop on the solid as in the case of the sessile drop technique.
