Abstract

We describe an instrument consisting of two adjacent Langmuir troughs and an apparatus capable of dipping substrates in either trough. Such a capability permits the fabrication of Langmuir-Blodgett multilayer films consisting of two alternating components. The troughs are housed in a hermetically sealed enclosure which may be evacuated to permit the establishment of a clean and/or modified (e.g., O₂ free) atmosphere. The enclosure is double walled for circulation of thermostating fluid (e.g., ethylene glycol) in order to establish temperatures in the range -30 to 130°C. The monolayer pressures, film size, and dipping sequence can be controlled manually or by a computer. The surface pressure in each trough is sensed by independent Cahn balances employing filter paper "Wilhelmy plates" in such a manner as to maintain the hermetic seal.
