ABSTRACT
Polyimides are widely used in the fields of microelectronics, electrical engineering, and chemical engineering. Much attention has recently been paid to ultrathin films along with progress in so-called “high technology.” The Langmuir-Blodgett (LB) technique is very attractive as a way of producing ultrathin films. In this technique, a single monolayer formed on water surface is transferred onto a solid subtrate layer by layer. The resulting mono- and multilayer films are called Langmuir-Blodgett films after the discoverers, I. Langmuir and K. Blodgett. The successful preparation of polyimide as Langmuir-Blodgett films should lead to new applications in the fields of microelectronics, electrical engineering, and chemical engineering.
