“…Hybrid organic-inorganic nanostructure composites based on polymer matrix and inorganic matter have attracted great interest of researchers because they exhibit the enhanced performance properties compared with conventional composites owing to the maximized interfacial contact between the organic and inorganic phases [8][9][10]. Graphene, as a novel inorganic material, attracts more interest in the area of polymer composites during the past few years owing to excellent characteristics such as high mechanical properties (approximately 1000 GPa) [11,12], excellent electrical conductivity (approximately 6000 S cm -1 ) [13], thermal conductivity (approximately 5000 Wm -1 K -1 ) [14], high surface area (2630 m 2 g -1 ) [15], and gas impermeability [16]; this implies that graphene as reinforcing agents may improve the drawback of WPU.…”

To study the dispersity of different amine-graphene oxide (amine-GO) in polymer matrix and the interfacial interactions between functionalized graphene oxide and matrix, two kinds of modifiers-organoamine-and aminosilane-coupling agents-were used to functionalize graphene nanosheets to obtain functionalized graphene oxide/waterborne polyurethane nanocomposites by in situ polymerization. The chemical structure, morphology, and interlayer space of amine-GO nanoplatelets were confirmed by FT-IR, Raman, TGA, XPS, TEM, AFM, and XRD. The dispersity behaviors between different amineGOs and polymers were evaluated by FESEM. The thermal, mechanical, and hydrophobic properties of the nanocomposites were investigated by TGA, tensile testing machine, and water contact angle test, respectively. It was found that the tensile strength of nanocomposites was increased from 10.13 to 27.79 and 28.96 Mpa after the addition of amine-GO functionalized by APTMS and APTES, respectively. The better thermal stability and hydrophobicity of nanocomposites were also achieved by the addition of amine-GO, especially those modified by aminosilane-coupling agents. This study paves a new route for designing and developing chemically converted graphene oxide nanosheets/polymer nanocomposite materials by altering suitable amine-modifier to functionalize graphene oxide nanosheets and then optimizing the interphases between graphene oxide nanosheets and polymer matrices.

“…This means that, latexes had high Ingredients binding capacity which is related to higher scrub resistance. In the same way, the compatibility of the ingredients with the commercial latex (PEXICRYL SA) seems to be [37]. For the black coating; the blackness perception for these coatings was found dependent on the addition of black pigment solution study, the reactivity of carbon black as additive to coatings towards ultraviolet radiation has been investigated and its incorporation into binder improved the UV resistance.…”

Nano-emulsions have unique properties such as small droplet size, robust stability, translucent appearance and tunable rheology. These properties make nano-emulsions an attractive candidate for applications in the paints industry. Nano-emulsion were prepared by semi-continuous method and, then the prepared emulsion Co-polymer of Styrene/2 Ethylhexyl acrylate and Ter-polymer of Styrene/methyl methacrylate/2-Ethylhexyl acrylate formulated and used as a binder for waterbased paints to improve physical properties against (UV irradiation, heavy rain, and discoloration of paint). Characterization of the prepared emulsions was performed using e.g. FTIR, TEM, DSC, TGA, and DLS. Nano-emulsions formed by using two different surfactants (anionic and nonionic surfactant) in presence of K 2 S 2 O 8-initiation and caused to making two acrylic emulsion polymers. Based on formulated this prepared polymer and their use as a binder for paint. The adhesion, surface hardness, gloss brightness, and water resistance were studied and evaluated. Also, the purpose of this study is to improve UV irradiation by exploring the influence of different compositions on the stability of waterborne paints. And modification of the flow behavior and structure in predictable way to control sag resistance, storage stability, spatter resistance and application behavior. Keywords Nano-emulsion polymer, Ter-polymer water-based paints, 2-Ethylhexyl acrylate drug delivery, food, cosmetics, pharmaceuticals, and material synthesis. Additionally, they serve as model systems to understand nanoscale colloidal dispersions. High and low energy methods are used to prepare nanoemulsions, including high pressure homogenization, ultra-sonication, phase inversion temperature and emulsion inversion point, as well as recently developed approaches such as

“…UV irradiation, water, and microorganisms are the main drivers of surface deterioration, resulting in color changes, cracks, and degradation . Wood surface treatments for weathering protection are commonly conducted with synthetic polymer coatings containing UV absorbers (e.g., nanoparticles) or hindered amine light stabilizers as well as various waxes . These treatments lead to a good protection, but the long‐term stability remains a problem as a protective polymer coating will be degraded as well by UV irradiation.…”

It is a challenging task to realize the vision of hierarchically structured nanomaterials for large-scale applications. Herein, the biomaterial wood as a large-scale biotemplate for functionalization at multiple scales is discussed, to provide an increased property range to this renewable and CO -storing bioresource, which is available at low cost and in large quantities. The Progress Report reviews the emerging field of functional wood materials in view of the specific features of the structural template and novel nanotechnological approaches for the development of wood-polymer composites and wood-mineral hybrids for advanced property profiles and new functions.
