Abstract:
An article with different surface properties on opposing sides is provided including a sheet having a first side and a second side, wherein the first side displays low adhesion properties, said first side comprising a roughened, porous or structured surface and a wetting liquid disposed upon the surface to form a stable liquid film; and wherein the second side displays a second property dissimilar from that of the first side. The article can be adhered to a variety of objects to impart anti-fouling properties.
Abstract:
A novel type of ultrathin cationic hydrogel coatings are provided that have high, quick and reversible swelling/shrinkage transitions and surface wettability in response to pH changes. The poly(4-vinyl pyridine) (PVP) hydrogel films are produced by selective cross-linking of PVP copolymers in layer-by-layer (LbL) films assembled by spin-assisted method. These multilayer hydrogels exhibit drastic and reversible 10-fold swelling when the pH is changed from neutral to acidic. The swelling amplitude of these coatings is controlled by varying cross-link densities within the films. The pH-responsive hydrogels open new prospects for developing “intelligent” materials with sharp stimuli-triggered responses for applications in sensing, transport regulation, and self-cleaning coatings.
Abstract:
A polycarbonate glazing includes a polycarbonate substrate and a silicon oxide-containing hard coating layer formed on one surface of the substrate, wherein the polycarbonate glazing has a haze difference (ΔHaze) of about 4.5 or less between before and after abrasion, as measured in accordance with ASTM D1003 after 500-cycle testing under conditions of a CS-10F abrasion wheel and a load of 500 g using a Taber Abraser, and has a water contact angle from about 40° to about 60°. The polycarbonate glazing may exhibit excellent abrasion resistance and transparency.

Abstract:
A method for providing a nanopattern of periodically ordered metal oxide nanostructures on a substrate is described. The method comprises the steps of providing a microphase separated block copolymer as a thin film on a substrate, the block copolymer comprising a first polymer having an affinity for a cations of the metal and a second polymer having a lower affinity for the cations than the first polymer, and selectively incorporating a salt of the metal cation into the first polymer of the block copolymer by means of a solvation process prior to or after formation of the microphase separated block copolymer. The block copolymer film is then treated to oxidise the metal ion salt and remove the polymers leaving a nanopattern of metal oxide nanostructures on the substrate.
Abstract:
The process of forming a partial gold-plating pattern on a stainless substrate includes a first plating step, a second plating step, and a stripping step. In the first plating step, pretreatment is applied to a stainless substrate including opposite main planes and a processing site formed of a plane different from the main planes, after which a first gold-plating layer is formed all over the surface of the stainless substrate using a hydrochloric acid plating solution. In the second plating step, mask plating is used to form a second gold-plating layer on the first gold-plating layer that covers the processing site in a desired pattern, and in the stripping step, a portion of the first gold-plating layer in an area where there is none of the second gold-plating layer is stripped off using an alkaline stripping solution.
Abstract:
