Tensiometer
Tensiometer
The Tensiometer is primarily used to determine the wettability of the surface. This analysis provides the contact angle, Surface tension, Interfacial tension, and critical micelle concentration of the material. This technique is working based on the principle of the intermolecular interaction between the solid surface and liquid. In these techniques, a contact angle is formed, when the liquid droplet is placed on the solid sample surface. Besides that, the surface energy and hydrophobic or hydrophilic nature of the material were determined using the contact angle.
There are two types of tensiometers- Optical tensiometer
- Force tensiometer
Tensiometers work by utilizing the interplay between the liquid’s surface tension and the forces at the point where the liquid, solid and surrounding vapour meet. A tiny droplet of the liquid is placed on the surface. The surface tension of the liquid acts like an elastic film, pulling inwards and minimizing the droplet’s surface area. At the contact point, there are attractive forces between the liquid molecules and the solid, along with the surface tension forces within the liquid itself. The balance of these forces determines how the droplet spreads on the surface, resulting in a specific contact angle. Tensiometers come in two main types: optical and Force tensiometer. Optical tensiometers capture an image of the droplet and analyse its shape to calculate the angle. Force or Wilhelmy plate tensiometers measure the force needed to pull a plate out of the liquid, which is related to the contact angle and the surface tension of the liquid.
