Webb23 feb. 2024 · A Langmuir–Blodgett 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. Many possible applications have been suggested over years for LM and LB films. Their characteristics are extremely thin films and high degree of structural order. These films have different optical, electrical and biological properties which are composed of some specific organic compounds. Organic compounds usually have more positive responses than inorganic materials for outside factors (pressure, temperature or gas change). LM films can be used also as models for …
Webbof the Langmuir-Blodgett trough. It is important to note that the displacement of the PVP capping agents with thiol ligands is critical in rendering the nanowire surface hydro-phobic as well as preventing aggregation. The assembly process is a microscopic version of “logs-on-a-river”. Figure 2A shows a photograph of the nanowires dispersed ... WebbThe sharp increase in surface pressure during compression is common in Langmuir–Blodgett assembled films of nanomaterials. 38 In response to compression the surface pressure profile in Scheme 1 (c) rises rapidly until it reaches a maximum due to the size of the sheets and the potential difficulty in sliding over each other compared to …
