The development of functional materials and the use nanotechnology are ongoing projects. These fields closely linked, but there is a need to combine them more actively. Nanoarchitectonics, concept that comes after nanotechnology, ready do this. Among related research efforts, into creating through formation thin layers on surfaces, molecular membranes, multilayer structures these have lot implications. Layered especially important as key part nanoarchitectonics. diversity components used in layer-by-layer (LbL) assemblies notable feature. Examples LbL introduced this review article include quantum dots, nanoparticles, nanocrystals, nanowires, nanotubes, g-C3N4, graphene oxide, MXene, nanosheets, zeolites, nanoporous materials, sol–gel layered double hydroxides, metal–organic frameworks, covalent organic conducting polymers, dyes, DNAs, polysaccharides, nanocelluloses, peptides, proteins, lipid bilayers, photosystems, viruses, living cells, tissues. examples assembly show how useful versatile it is. Finally, will consider future challenges

ABSTRACT In pursuit of multifunctional flame‐retardant coatings, a layer‐by‐layer (LbL) assembly was used to create hybrid nanocoatings by alternating the deposition positively charged chitosan (CH) and negatively sodium lignosulfonate (Lg). Carbon nanotubes (CNT), dispersed in an Lg solution, were incorporated as robust reinforcements polymer nanocomposites. Their high aspect ratio dense network within CH/CNT‐Lg layers resulted coatings that notably thicker heavier compared those constructed without CNT. horizontal flame tests, presence CNT led superior fire resistance. Cone calorimetry further demonstrated incorporating into single coating completely suppressed second peak heat release for polyurethane foam (PUF). Additionally, total smoke release, production, maximum average rate emission, effective combustion reduced 68.9%, 72.7%, 47.7%, 57.3%, respectively, uncoated PUF. These improvements retardancy are attributed enhanced thermal stability char yields provided Overall, given ease applying LbL assembly, this strategy offers promising halogen‐free approach improving safety both natural synthetic fibers.
