4 - Nanostructured Films: Langmuir–Blodgett (LB) and Layer-by-Layer (LbL) Techniques

Add time:09/04/2019    Source:sciencedirect.com

This chapter discusses the historical and technological development of two important techniques for fabricating ultrathin films: Langmuir–Blodgett (LB) and layer-by-layer (LbL) methods. For the LB method, the theoretical aspects of characterizing Langmuir monolayers by pressure and surface potential are presented, and the transfer ratio and types of LB films obtained during deposition are reviewed. For the LbL technique, the physical and chemical processes involved in the film formation, the different types of interactions between materials, and the spray- and spin-assisted LbL methodologies for film production are discussed. Applications of the LB and LbL techniques are cited to illustrate their use in various fields.
