Surface Tension, Capillary Action, and Viscosity

30.9K
Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Main Methods:

  • Literature review of natural and artificial responsive surfaces.
  • Analysis of surface wettability and adhesion properties.
  • Categorization of surfaces based on stimuli response (stretching, magnetic, photo, electric, temperature, humidity, pH).

Main Results:

  • A new classification of droplet states on surfaces is proposed.
  • Diverse smart surfaces responding to various stimuli are discussed, including those for atmospheric and underwater applications.
  • Key applications in microfluidics, liquid transport, water harvesting, and flexible devices are highlighted.

Conclusions:
