Langmuir–Blodgett film

Show Summary Details

Quick Reference

A film of molecules on a surface that can contain multiple layers of film. A Langmuir-Blodgett film with multiple layers can be made by dipping a plate into a liquid so that it is covered by a monolayer and then repeating the process. This process, called the Langmuir-Blodgett technique, enables a multilayer to be built up, one monolayer at a time. Langmuir-Blodgett films have many potential practical applications, including insulation for optical and semiconductor devices and selective membranes in biotechnology.
