Light incident on an oil film on water. In the case of a thin oil film, a layer of oil sits on top of a layer of water. The oil may have an index of refraction near 1.5 and the water has an index of 1.33. As in the case of the soap bubble, the materials on either side of the oil film (air and water) both have refractive indices that are less ...
Alternatively, a catenoid can be formed by dipping two rings in the soapy solution and subsequently separating them while maintaining the coaxial configuration. Stationary fluid films form surfaces of minimal surface area, leading to the Plateau problem. On the other hand, fluid films display rich dynamic properties. They can undergo enormous ...
Soap films are thin layers of liquid (usually water-based) surrounded by air. For example, if two soap bubbles come into contact, they merge and a thin film is created in between. Thus, foams are composed of a network of films connected by Plateau borders. Soap films can be used as model systems for minimal surfaces, which are widely used in ...
Window tinting refers to the process of applying a thin laminate film to a vehicle's glass in order to darken it. The reasons people choose to tint the windows of an automobile vary.

The thicker window films known as safety and security window film are designed to perform under extreme conditions, and as such there are specific standard criteria these films should meet, such as American standards ANSI Z.97, CPSC 16 CFR 1201, Cat II (400 ft-lb), and the British Standards BS 6206 (Class A, B, C).
The first self-cleaning glass was based on a thin film titania coating. [3] The film can be applied by spin coating of organo-titanate chelated precursor (for example titanium iso-tetrapropoxide chelated by acetylacetone), followed by heat treatment at elevated temperatures to burn the organic residues and to form the anatase phase.
The sol-gel process is a common method of preparing water-repellent glass coating films done with various materials and often resulting in dual-layer films. [7] This process is advantageous for automobile window applications since it works with large, curved safety glasses and allows qualities such as durability and hydrophobicity to be controlled.
