Organic film is a thin layer of organic material that is deposited on a substrate and used in various crucial applications. Some common synonyms for organic film include thin films, coatings, layers, sheets, membranes, and platings. These materials can be fabricated by various techniques such as evaporation, sputtering, and chemical vapor deposition. Organic films have extensive applications in fields like electronics, optics, energy storage, biosensors, and membrane filtration. Conductive polymers, metal-organic frameworks, and graphene are some examples of materials that are widely used in organic film technology. The properties and applications of organic films depend on the choice of substrate, deposition technique, and choice of organic material.
