A nanocomposite structure includes: a) a charged fibrous substrate including fibers having disposed on their surfaces a multilayer structure including a layer of a first polyelectrolyte and disposed thereon a layer of a second polyelectrolyte of opposite charge from the first, the second polyelectrolyte forming the outermost layer of the charged fibrous substrate; and b) charged nanorods having a charge opposite that of the charged fibrous substrate, including gold nanorods each having disposed on its surface one or more layers, the outermost of which is a third polyelectrolyte having a charge opposite that of the second polyelectrolyte, wherein the first and third polyelectrolytes may be the same or different; wherein the charged nanorods are disposed unaligned with respect to each other on the charged fibrous substrate.

A method, and an article made therefrom, of: contacting a substrate with a first solution of a first polyelectrolyte polymer to form a layer of the first polyelectrolyte polymer on the substrate; and contacting the layer of the first polyelectrolyte polymer with a second solution of a second polyelectrolyte polymer to form a layer of the second polyelectrolyte polymer on the layer of the first polyelectrolyte polymer. The first polyelectrolyte is a polyanion or polycation polymer. The second polyelectrolyte is a polyanion or polycation polymer of a charge opposite to that of the first polyelectrolyte polymer. At least one of the first solution or the second solution is an aggregate-forming solution comprising an ionic species having at least two discrete sites of a charge opposite to that of the polyelectrolyte polymer in the aggregate-forming solution. The ionic species forms, via bridging interactions, aggregates of the polyelectrolyte polymer that remain intact in the aggregate-forming solution during the contact and layer formation.

A coating method of reflective film is first to prepare a glass beads film and then select a color to be coated. The color is composed of plural primary colors in fixed ratio, making the color have a standard ratio, which is obtainable from an original database. Next, ratios of the primary colors are respectively adjusted to form a printing ratio according to color fastness, permeability and light barrier property of each primary color attached to the glass beads and then, each primary color is orderly spray coated on the glass beads film to form a coating layer with micro-printing technique in accordance with the printing ratio, thus completing manufacturing of a reflective film with high transmittance and high wide angle.

A coated substrate including: a substrate including a treated layer, a photocatalytic layer, and a protective layer between the photocatalytic layer and the treated layer, the protective layer comprising colloidal particles dispersed in a matrix, the colloidal particles including first and second types of particles that differ in their respective particle size distributions and which together provide a physical barrier by virtue of the first, smaller particles at least partially filling interstices between the second, larger particles and thereby impede photocatalyst derived degradation of the treated layer, the first type of colloid particles comprising hydrolyzed silica based material such as reactive silica condensate particles or polyhedral oligomeric silsesquioxanes, or mixtures thereof, the protective layer having an effect of less than 20 delta E units on the color and gloss of the substrate.
