A variant of self-assembly is the assembly occurring at the gas–liquid interface. The Langmuir monolayer (LM) is a monolayer formed in this way. The LM can be transferred to a solid substrate to form a Langmuir–Blodgett (LB) membrane. In LB technique, molecular organization precedes adsorption …Langmuir monolayers were transferred onto solid glass substrates by using the Langmuir–Blodgett technique. The absorption spectra of the BTD films are depicted in Fig. 7 . The absorption bands between 360 and 420 nm do not change in comparison to the absorption spectra in solution as shown in Fig. 2 .If one of the blocks strongly favors one of the two interfaces, or even both, the lamellae will be parallel to the substrate. The classic example is PS-b-PMMA on a Si wafer covered with the native oxide [Anastasiadis].The signature of parallel lamellae in GISAXS are stripes of intensity at regular spacings along the q z direction. In Langmuir-Blodgett films, such …

Many technological applications require templates with nanoscale patterns. Block copolymer self-assembly is a method of choice for obtaining a large variety of such patterns, with greatest flexibility achieved when combined with a supramolecular approach. One of the ways to fabricate block copolymer templates is the Langmuir-Blodgett (LB) …Using the Langmuir–Blodgett (LB) technique, a simple method for depositing antibacterial nanoparticles of various shapes, sizes, and compositions onto MNs is developed. This strategy has merits over conventional dip coating techniques, including controlled coating layers, uniform and high coverage, and a straightforward fabrication process.
