“…[47][48][49][50][51] Recently, a large number of functional electrodes have been developed through alternating assembly of positively-charged LDH nanosheets and negatively-charged species (small molecules, metal complex, macromolecules or polymers) or anionic nanoparticles (Au, CdS or graphene oxides GO). LDH microcrystals can be exfoliated into positively-charged 2D monolayer sheets, which are assembled alternately with various functional anions by the LBL technique.…”

Two-dimensional (2D) materials have attracted increasing interest in electrochemical energy storage and conversion. As typical 2D materials, layered double hydroxides (LDHs) display large potential in this area due to the facile tunability of their composition, structure and morphology. Various preparation strategies, including in situ growth, electrodeposition and layer-by-layer (LBL) assembly, have been developed to directly modify electrodes by using LDH materials. Moreover, several composite materials based on LDHs and conductive matrices have also been rationally designed and employed in supercapacitors, batteries and electrocatalysis with largely enhanced performances. This feature article summarizes the latest developments in the design, preparation and evaluation of LDH materials toward electrochemical energy storage and conversion.

“…Kotov et al successfully fabricated stiff and ultrastrong nanocomposites by assembling alternately with montmorillonite (MMT) nanosheets and polyvinyl alcohol (PVA) aqueous solution, which upsurges a target for preparation nanocomposite materials via layer-by-layer self-assembly method (LBL method) [5][6][7]. As successful exfoliation of layered double hydroxides (LDHs), positively-charged LDHs nanosheets have been widely used as building blocks [8][9][10][11][12][13][14][15].…”

Layered double hydroxides (LDHs), luminescent π-conjugated anionic polymer and montmorillonite (MMT) were orderly assembled into luminescent multilayer films via layer-by-layer self-assembly method. The electronic microenvironment (EME), the structure of which is like a traditional capacitor, can be constructed by exfoliated LDHs or MMT nanosheets. In addition, the rigid inorganic laminated configuration can offer stable surroundings between the interlayers. As a result, we conclude that EME can extend the luminescent lifespans of multilayer films substantially, due to affecting relaxation times of π-conjugated anionic polymer. Consequently, because of the remarkable impact on better photoemission behaviors of luminescent π-conjugated anionic polymer, EME assembled by LDHs or MMT nanosheets have had high hopes attached to them. They are expected to have the potential for designing, constructing, and investigating novel light-emitting thin films.

“…Because of the extensive applications of PVA, many attempts have been made to improve the properties of this polymer or PVA/clay nanocomposites [16][17][18][19][20][21][22]. Kim et al [23] investigated the effects of clay content and its cation type on the thermal stability, water uptake, and transport properties of PVA/clay hybrid membranes.…”

Poly(vinyl alcohol) (PVA)/montmorillonite nanocomposites were prepared via solution polymerization. The nanocomposites were formed either by first hydrolyzing poly(vinyl acetate) (PVAc) to PVA and then preparing the PVA/clay, or by initially preparing PVAc/clay and then hydrolyzing the matrix to PVA. The morphology of the nanocomposites was examined by X-ray diffraction and transmission electron microscopy, which suggested the proper dispersion of silicate layers within the PVA matrix. The influences of some variables including method of preparation, clay content, and time and temperature of saponification on the tensile properties (elastic modulus, stress and elongation at break) of the nanocomposite samples were investigated by using the Taguchi experimental design approach. The results indicated that the tensile properties of the nanocomposites improved as clay content, and the temperature and time of saponification increased. Effect of each factor on the ultimate properties of as prepared nanocomposites are discussed in detail. The analysis of variance (ANOVA) showed that the method of preparation did not influence the ultimate tensile properties of the nanocomposite samples.
