Ultraviolet (UV) absorbing inks and films for surfaces such as glass and/or plastic are provided that include patterns visible to avian eyes, but invisible to a human at least ten feet away. Such invention is aimed at reducing the number of window strikes that result in bird deaths. A formulation may include a binder, a carrier. A formulation may include a base configured to dissolve and solubilize the binder such that it can be applied to the carrier. A formulation may include at least one of an ultraviolet (UV)/visible (VIS) absorbing (UAC) component and a UV/VIS reflective (URC) component.

A quantum-dot light conversion film, a preparation method and an application thereof and an anti-ultraviolet blue-free yellow light for chip manufacturing are provided. The preparation method includes: (1) mixing a quantum-dot concentrate with an acrylic monomer, then adding high polymer for secondary mixing, to obtain a polymer; (2) after mixing the polymer and nanoparticles, adding additives for dispersion to obtain a light conversion liquid resin; and (3) coating and curing the light conversion liquid resin to obtain a quantum-dot light conversion film. The light conversion film has high light conversion efficiency, adjustable emission peak position and narrow half peak width. Its surface forms a tightly arranged high refractive index microlens structure. When the light reaches the microlens array, as the light output surface is a lens structure and the refractive index is improved, more light is emitted in the positive direction, thereby effectively improving the light output rate.

The composite material has a reflectivity in the visible spectrum of electromagnetic radiation that is less than or equal to 10.0%, and a reflectivity in the near-IR and LiDAR spectrum of electromagnetic radiation that is greater than or equal to 12%.

The present disclosure relates to an aqueous coating composition for forming a thermal insulation coating for walls and a reflective thermal insulation coating system for walls containing the thermal insulation coating. In particular, the aqueous coating composition comprises, based on the total weight of the aqueous coating composition, at least 65 wt % of an aqueous dispersion of polymer particles; at least 5 wt % of expanded organic polymer micro-beads; at least 10 wt % water; and 0 to 15 wt % of additional additives, comprising thickeners, dispersants, wetting agents, defoamers, pH adjustors, film-forming aids, hydrophobic agents, coupling agents, bactericides, and antifungal agents or any combination thereof.

Provided is a polyimide varnish comprising: polyamic acid and nanosilica, wherein the nanosilica contains 5 to 23 wt % relative to the solid content of the polyamic acid, and the polyimide varnish has an absolute value of zeta potential of 1 to 30 mV.

A method for internal and external collaborative integrated protection of concrete is provided. The method has two aspects: first, combining reinforcement with cement and significantly enhancing compactness and strength of the concrete through a special surface treatment process; and second, successively constructing dual rough structures at microscopic and nanoscopic levels on the surface of the concrete through a super-hydrophobic anti-corrosive coating technology to form an efficient super-hydrophobic coating. The method effectively resists the erosion from external environments, solves problems such as carbonation of concrete, sulphate attack and corrosion of steel bar, and provides a high-performance and long-life concrete material solution for the field of civil engineering.

Metal nanoparticle agglomerates may render the surface of an article biocidal toward microorganisms. Articles having a biocidal surface may comprise a coating comprising metal nanoparticle agglomerates adhered via an adhesive to at least a portion of a surface of the article. A coating formulation comprising metal nanoparticle agglomerates may be applied to the surface of an article to accomplish the foregoing.

The disclosure relates to the coating of a Light Emitting Diode (LED) lighting tube or the like to diffuse and reduce spotting along with glare that is produced by the individual LEDs within the unit. More specifically, the disclosure relates to coating intended for use with LED light sources and for allowing the transmission of radiation in the ultra-violet (UV) range of 315 to 400 mm (UV-A), 280-315 mm (UV-B) and 100-280 nm (UV-C) wavelengths, also suitable for visible lights LEDs at 400 to 700 nm wavelengths.
