WebbFlexible accessories for the Langmuir Trough include; dip coaters allowing thin film (monolayer) deposition on varying surfaces, Surface Potentiometer for surface potential … A Langmuir–Blodgett trough (LB trough) is a laboratory apparatus that is used to compress monolayers of molecules on the surface of a given subphase (usually water) and measures surface phenomena due to this compression. It can also be used to deposit single or multiple monolayers on a solid substrate. Visa mer Overview The idea of a Langmuir–Blodgett (LB) film was first proven feasible in 1917 when Irving Langmuir (Langmuir, 1917) showed that single water-surface monolayers could be transferred … Visa mer One of the first scientists to describe and attempt to quantify the spreading of monolayer films on the surface of a liquid was Benjamin Franklin. Franklin described the spreading of a drop of oil onto the surface of a lake to form a surface of defined area. In … Visa mer • Langmuir, I. (1920).
