The Use of Layer‐by‐Layer Self‐Assembly and Nanocellulose to Prepare Advanced Functional Materials

Abstract

The current knowledge about the formation of layer‐by‐layer (LbL) self‐assemblies using combinations of nanocelluloses (NCs) and polyelectrolytes is reviewed. Herein, the fundamentals behind the LbL formation, with a major focus on NCs, are considered. Following this, a special description of the limiting factors for the formation of LbLs of only NCs, both anionic and cationic, and the combination of NCs and polyelectrolytes/nanoparticles is provided. The ability of the NCs and polyelectrolytes to form dense films with excellent mechanical properties and with tailored optical properties is then reviewed. How low‐density, wet stable networks of cellulose nanofibrils can be used as substrates for the preparation of antibacterial, electrically interactive, and fire‐retardant materials by forming well‐defined LbLs inside these networks is then considered. A short outlook of the possible uses of LbLs containing NCs is given to conclude.

A Bidimensional Gay-Berne Calamitic Fluid: Structure and Phase Behavior in Bulk and Strongly Confined Systems

“…An outstanding matter with an eye toward 3D metamaterials is how disclinations couple when colloidal slabs are stacked. Practicable systems could extend layer-by-layer protocols [7,89,90,[168][169][170][171][172][173][174][175][176][177][178][179][180], thus expanding the gamut of metamaterials attainable by conventional 3D-based methods. Studies on the switching mechanics by applying external fields (as opposed to thermal tempering) would be of interest in the production of devices and associated technologies.…”

Surface Properties of Spray-Assisted Layer-By-Layer ElectroStatic Self-Assembly Treated Wooden Take-Off Board

“…The development of wood coatings could benefit from nanotechnological methods, such as polyelectrolyte layer-by-layer (LbL) self-assembly. Over the past few decades, electrostatic LbL assembly has been developed as a simple, practical, and versatile method [15][16][17]. It creates thin films with desirable layer composition (in the nanometer range) both on large surfaces and on microfibers and cores.…”

Anticoagulant Activity of Cellulose Nanocrystals from Isora Plant Fibers Assembled on Cellulose and SiO2 Substrates via a Layer-by-Layer Approach

“…These comprise their biocompatible or bioactive coatings, biosensors, drug-delivery, cell encapsulation and protein delivery, optically active surfaces, protein-repellent and many others [ 3 ]. It can generally be prepared by sequential deposition of polycations and polyanions on various solid substrates [ 4 ]. PEMs based on renewable materials, including nanoclays [ 5 ], proteins [ 6 ], polysaccharides [ 3 , 7 , 8 ], have been successfully incorporated via electrostatic interactions with charged synthetic polymers [ 5 , 9 ].…”
