Embodiment Construction

[0058] figure 1 Primarily a nanostructured product 100 with a structurally colored surface is shown. The nanostructured product 100 is shown in top view (lower view) and in cross-section along line AA (upper view).

[0059] The product 100 includes a substrate 101 comprising a nanostructured surface with raised or depressed nanostructures 102 , ie, nanosized structural features 102 . Thus, the nanostructures 102 can be considered as elongated structures, such as needles or holes, protruding from or into the substrate. figure 1 The raised structure is shown. The elongated structure may have a circular, square, hexagonal or other cross-sectional shape in a plane perpendicular to the longitudinal direction of the elongated structure. The nanostructured surface defines a base plane 105, which may be a generally flat surface or a curved (eg, doubly curved) surface, and the nanostructures 102 are convex into or out of the base plane 105.

Abstract

The invention relates to a nanostructured product with a structurally coloured surface. The nanostructured product includes a substrate with a nanostructured surface having nano-sized pillars or holes arranged in a periodic pattern and extending into or out from the substrate. The bottoms of the nano-sized holes or the tops of nano-sized pillars are provided with metal layers electrically isolated and distanced from a base surface of the nanostructured surface. A transparent or translucent protective layer covers the substrate and the metal layers.

Description

technical field [0001] The present invention relates to nanostructured surfaces and in particular to structural coloring using such surfaces. Background technique [0002] It is known to decorate plastic objects by painting them with colored paint materials. Paint will bond to the object as it dries. Other methods exist for providing colored decoration to plastic objects. Typically, this method complicates the manufacturing process of plastic objects, since the process includes various steps for applying the device in addition to forming the plastic object. [0003] In addition, because the paint may otherwise add undesired coloration to the recycled material (for example, the white of the primary material will be stained with black paint), the paint needs to be removed before the primary object can be recycled, whereby colored products Complicating the recycling of this product. [0004] Accordingly, there is a need for other coloring processes for decorating objects th...
