Disclosed are articles that are provided with a haptically-perceptible surface. The articles include a coated glass or glass ceramic substrate which is provided with a layer with haptic properties so that the layer has a haptically perceptible texture. The layer includes texturing inorganic and/or polysiloxane-based particles which are fixed on the substrate by a layer-forming material. The particles cause protrusions on the layer and so produce the haptically perceptible texture.

A transparent conductive film includes a film base, a cured resin layer formed at one side of the film base, and an indium composite oxide layer laminated at a side of the cured resin layer opposite to the film base. The indium composite oxide layer has a thickness of 20 nm to 50 nm. The cured resin layer has a plurality of spherical particles and a binder resin layer which fixes the plurality of spherical particles to the film base. A difference w−d between a mode particle size w and a thickness d of the binder resin layer is greater than zero and less than or equal to 1.2 μm, where w is a mode particle size of the spherical particles and d is a thickness of the binder resin layer.

Variations of this invention provide durable, impact-resistant structural coatings that have both dewetting and anti-icing properties. The coatings in some embodiments possess a self-similar structure that combines a low-cost matrix with two feature sizes that are tuned to affect the wetting of water and freezing of water on the surface. Dewetting and anti-icing performance is simultaneously achieved in a structural coating comprising multiple layers, wherein each layer includes (a) a continuous matrix; (b) discrete templates dispersed that promote surface roughness to inhibit wetting of water; and (c) nanoparticles that inhibit heterogeneous nucleation of water. These structural coatings utilize low-cost, lightweight, and environmentally benign materials that can be rapidly sprayed over large areas using convenient coating processes. The presence of multiple layers means that if the surface is damaged during use, freshly exposed surface will expose a coating identical to that which was removed, for extended lifetime.

A molding packaging material including a matte coat layer having excellent formability, chemical resistance, solvent resistance, and printability is provided. The molding packaging material 1 includes an outer base material 13 made of a heat-resistant resin, an inner sealant layer 16 made of a thermoplastic resin, a metal foil layer 11 arranged between the outer base material 13 and the inner sealant layer 16, and a matte coat layer 14 formed on one side of the outer base material opposite to the other side thereof to which the metal foil layer 11 is arranged. The matte coat layer 14 is made from a resin composition containing a base compound resin including a phenoxy resin and a urethane resin, a curing agent, and solid fine particles.

Disclosed herein is a substrate having a surface modified to impart multi-scale roughness, thereby providing superhydrophobic and/or superoleophobic properties. The surface comprises a pattern of microscale pillars topped by a plurality of nanoparticles having a re-entrant convex shape. The area fraction of the surface is also selected to provide the desired superoleophobic properties. Also disclosed herein is a process for creating the modified surface comprising photolithography, optionally followed by vapor deposition. The substrates may be formed into useful articles or applied to pre-formed articles.

The present disclosure relates, according to some embodiments, to articles, systems, and methods for roofing a structure including, for example, layered shingles comprising a plurality of layers. A layered shingle may comprise, in some embodiments, an upper layer and a backing layer comprising a low density aggregate, wherein the backing layer is fixed to the substrate-facing surface of the upper layer.
摘要:
A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.
摘要:
A process for providing indicia and an elastic-like behavior to a web substrate is disclosed. The process comprises the steps of: providing a web substrate; printing indicia on the web substrate; and, providing the web substrate with a plurality of first regions and a plurality of second regions comprising the same material composition. A portion of the first regions extend in a first direction while the remainder of the first regions extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions comprise a plurality of raised rib-like elements. The first regions undergo a molecular level and geometric deformation and the second regions initially undergo a substantially geometric deformation when the web material is subjected to an applied elongation along at least one axis.
