What is Langmuir-Blodgett deposition?
7,17) Langmuir–Blodgett (LB) deposition is a reliable technique for depositing well-defined films of various nanoparticles, (18−20) and the technique also offers better control over GO depositions. (
What is Langmuir-Blodgett technique?
The Langmuir-Blodgett (LB) technique is a way of making supra-molecular assembly in ultrathin films with a controlled layered structure and crystal parameter, which have many envisioned technological applications for optical and molecular electronic devices as well as signal processing and transformation.
What is Langmuir-Blodgett film used for?
Langmuir Films are thin organic films of a thickness of just one molecule and are the source of high expectations. As useful components in many practical and commercial applications such as sensors, detectors, displays and electronic circuit components.
What is the difference between Langmuir film and Langmuir-Blodgett film?
When a monolayer is fabricated at the gas-liquid or liquid-liquid interface, the film is a Langmuir film. A Langmuir film can be deposited on a solid surface and is thereafter called Langmuir-Blodgett film (in the case of vertical deposition) or Langmuir-Schaefer film (in the case of horizontal deposition).
How does a Langmuir trough work?
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.
What are Langmuir monolayers?
A Langmuir monolayer or insoluble monolayer is a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail.
What is the Langmuir film balance?
THE Langmuir–Adam film balance was developed to measure the lowering of surface tension (termed the surface pressure) produced by paraffin-chain compounds such as oleic acid when spread as monolayers on aqueous solutions.
