Thin films are thin layers of a liquid in which their length is much greater than their thickness. Important examples of thin films include soap bubbles, and thin films between solids for lubrication. Capillary forces are also very important in governing the physics of thin films - for more information go to Capillarity and wetting.

The study of thin films will play a large role in mechanics research in the future.
