Recent Applications of Langmuir–Blodgett Technique in Battery Research

Abstract

The Langmuir–Blodgett (LB) technique, in which monolayers are commonly transferred from a liquid/gas interface to a solid surface, allows convenient fabrication of highly ordered thin films with molecular-level precision. This method is widely applicable to substances ranging from organic molecules to nanomaterials. Therefore, LB methods have provided a critical toolbox for researchers to engineer nanoarchitectures. The LB fabrication process is also compatible with numerous substrate materials over large areas, which is advantageous for practical application. Despite its wide applicability, the LB strategy has not been extensively employed in battery studies. The versatility of LB film, along with the accumulated knowledge associated with this technique, makes it a promising platform for promoting battery chemistry evolution. This Review summarizes recent advances of LB methods for high-performance battery development, including preparation of electrode materials, fabrication of functional layers, and battery diagnosis and thus illustrates the high utility of LB approaches in battery research.

Materials nanoarchitectonics in a two-dimensional world within a nanoscale distance from the liquid phase

“…Nanoarchitectonics is particularly suited for the fabrication of hierarchical structures because it combines processes that include not only the self-assembly of components but also human manipulation, such as the Langmuir–Blodgett (LB) method, 29 layer-by-layer (LbL) assembly, 30 and various microfabrication methods. 31 The high capability of nanoarchitectonics for the fabrication of hierarchical functional structures 32 shares features of structural constructions seen in biological systems in which huge numbers of functional components are hierarchically organized and their functions are linked together.…”

Photoinduced modulation of refractive index in Langmuir-Blodgett films of azo-based H-shaped liquid crystal molecules

“…In the field of sensors, it has been reported that organized and ultrathin nature of LB films of materials can offer a large enhancement in sensing parameters as compared to randomly oriented thick films [19,20]. The LB films can be used for non-linear optical devices, photovoltaics, ultrafiltration membrane, molecular electronic, and energy storage devices [21][22][23]. The shapeanisotropic liquid crystal molecules at the air-water interface show very interesting results.…”
