“…There are two main categories for these types of stabilizing agent a follow: Thiols (Sulfur-containing compounds): Thiols (R-SH) can form strong covalent bonds with certain metal surfaces, such as gold, silver and Platinum NPs. [103][104][105][106][107][108][109] The sulfur atom in the thiol group has a lone pair of electrons that can coordinate with metal atoms on the nanoparticle surface, forming metal-sulfur bonds.…”

This review comprehensively analyzes the challenge of dispersing and stabilizing of various common nanomaterials (NMs), including TiO₂, SiO₂, Ag, ZnO, graphene, carbon nanotubes (CNTs) and some others, in paints and coatings. It delves into the critical factors influencing dispersion, such as nanoparticle size, shape, concentration, and their distribution within the coating matrix.The review encompasses all stages of dispersion methods, including wetting, separation techniques, and stabilization. Regarding stabilization, both chemical and physical stabilization methods are discussed, along with their mechanisms, involving surface modification or functionalization of NMs, particularly tailored for aqueous and solvent‐based coatings and common resins (Acrylic, Urethane, Epoxy, Alkyd, etc.). Furthermore, common blending methods to fabricate uniform paints, coatings, and nanocomposites (NCPs) are examined. By providing a comprehensive understanding of the mechanisms governing NM dispersion and stabilization, this review facilitates the selection of appropriate surface modifications based on the specific resins or solvents, thereby enabling the fabrication of high‐performance paints and coatings. In summary, this review elucidates the essence of addressing the challenges associated with NM dispersion and stabilization, outlines methodologies employed, discusses findings regarding their effects on coating properties, and recommends tailored approaches for fabricating high‐performance paints and coatings.

“…Coordination polymers possess a characteristic structure containing metal cation centers linked by ligands. [67][68][69][70][71][72] Although the self-assembly of nanoscale building blocks to generate highly ordered coordination polymers can benefit conductivity, [68,69] their high absorbance in the visible range [70][71][72] poses a hindrance to the fabrication of highly transparent electrodes. Jin et al reported the fabrication of a transparent coordination polymer by employing a 2D metal-organic framework (2D-MOF), namely Cu-BHT (BHT = benzene hexathiol); however, the low optoelectronic properties of the fabricated electrode need to be improved.…”

their use in large-scale applications. [2] Thus, a second generation of solar cells based on other inorganic materials, such as cadmium telluride (CdTe)/cadmium indium gallium diselenide (CIGS), have been developed; however, their practical applications are restricted by the toxi city and scarcity of the materials, along with their high production cost. [3,4] Consequently, OSCs, dye-sensitized solar cells (DSSCs), [5,6] and perovskite solar cells (PSCs) [7-9] have been developed, which are considered as third-generation SCs. Among the solar cells of the third generation, OSCs received significant attention due to their flexibility, low cost, and ease of fabrication, [10] which combined with their high efficiency, significantly contribute to the commercialization of FOSCs. Mass production of flexible OSCs is possible by using a roll-to-roll process, which enables the fabrication of wearable devices. [11,12] Potential applications of FOSCs include wearable devices, [13] space applications, [14] rechargeable bags and tents, and solar airships. One of the main components for fabricating FOSCs is TCEs, which play a key role in achieving high-performance OSCs, where current and light transmissions are simultaneously enabled. [15] Generally, the following characteristics are required for achieving a high-performance transparent electrode: [16-18] 1) high optical transmittance for permitting photons to reach and be absorbed within the active layer; 2) low sheet resistance for decreasing the resistance of solar cells; 3) low surface roughness for avoiding electrical shortage In this review, silver nanowires (AgNWs) are introduced, as the primary material to replace indium tin oxide for fabricating cost-effective flexible organic solar cells (FOSCs), because of their remarkable solution-processing, flexibility, transparency, and conductivity, along with their enhanced properties in terms of light-scattering, plasmonic effects, and transmittance in the near infrared region. The drawbacks of AgNWs, particularly their high roughness, low adhesion to substrates, atmospheric corrosion, degradation under UV and visible light, and poor contact at wire-wire junctions, must be resolved prior to their use in commercial FOSCs applications. Herein, comparisons among all candidates (e.g., graphene, carbon nanotubes, metal grids, and conducting polymers), along with a report of all recent progress in addressing these issues for using AgNWs as flexible transparent conductive electrodes (TCEs), are discussed. In addition, recent publications on the fabrication of highly efficient FOSCs based on AgNWs are summarized. The discussed issues regarding AgNWs-TCEs apply not only to FOSCs, but can be generalized for other third-generation solar cells, such as perovskite solar cells and dye-sensitized solar cells; additionally, they provide insight for other optoelectronic applications, such as organic light-emitting diodes, liquid crystal displays, smart windows, touch panels, and heaters.
