Layer-by-Layer Assembly for Graphene-Based Multilayer Nanocomposites: Synthesis and Applications

Abstract

graphene sheets have become a versatile platform for the fabrication of innovative hybrid materials with various functions due to their unique electrical, optical, thermal, and mechanical properties. The preparation of graphene-based composites with nanoscale precision is highly important for reproducible and controllable performance through the analysis of interplay between each component. In particular, the layer-by-layer (LbL) assembly technique is known as a simple, inexpensive, and versatile process for the fabrication of highly ordered multilayer film structures from various types of materials. The LbL structures capable of controlling nanoscale composition and architectures are achieved through the sequential adsorption of oppositely charged components by attractive forces such as electrostatic interactions. In this review, we will focus on the recent progress in graphene-based nanocomposites hybridized with various nanomaterials such as carbon nanomaterials, polymers, and inorganic nanoparticles by the LbL assembly. Multilayered graphene nanocomposites exhibit improved physical/chemical properties and superior performance compared with the individual components due to the synergistic effects in various applications including electric devices, energy storage and conversion, and biological usages.

Supercritical Fluid‐Facilitated Exfoliation and Processing of 2D Materials

“…2D materials have been extensively developed as wet chemical and gas phase sensors, and reviews of their applications focusing on GO, [242,243] rGO, [243] and graphene, [243,245] chalcogenides, [244][245][246][247][248][249] oxides, [248] and layer-by-layer [242,250] assemblies are available. In all electrochemical-based sensing, it is important to maintain good electrical conductivity in a sensor-intended composite material, similarly to 2D materials used in electrocatalysis.…”
