The invention relates to a method for surface treating a substrate (28) by means of an electrical corona discharge, wherein aerosols (5) are sprayed into discharge area defined by an active gap formed between a corona electrode and the substrate (28) during the discharging, designed such that the aerosols (5) are sprayed substantially opposite the direction of gravity.

The present invention relates to a device (10) for actuating a mobile part (21) of a motor vehicle (20) particularly a door, a hatch flap or such like, comprising a handle element (30),

characterized in that

the handle element (30) is at least partially configured from a composite material (40) which comprises a plastic material with a water absorption of less than 1% and a fibre material.

An article includes a first portion including a silicone polymer; a second portion adjacent to the first portion, wherein the second portion includes a thermoplastic polymer including a functional moiety that forms a chemical bond with the silicone polymer. A method of forming an article includes providing a first portion including a silicone polymer; providing a second portion adjacent to the first portion, wherein the second portion includes a thermoplastic polymer including a functional moiety that forms a chemical bond with the silicone polymer; and curing the first portion at a temperature lower than the heat deformation temperature of the thermoplastic polymer to form the chemical bond between the functional moiety of the second portion and the silicone polymer of the first portion.

A laminate (1) provided with: a substrate (2); an undercoat layer (3), which is formed on at least a portion of the outer surface of the substrate (2), contains an organic polymer with a functional group, and is formed in a membrane form or film form; and an atomic layer deposition film (4), which contains a precursor (6) that serves as a starting material, is formed so as to cover the surface of the undercoat layer (3), and in which at least some of the precursor (6) are bonded to the functional groups. The linear expansion coefficient of a layered film provided with the substrate (2) and the undercoat layer (3) is from about 1.0×10.sup.−5/K to about 8.0×10.sup.−5/K.

A method of modifying substrate surface includes: performing an O.sub.2 plasma treatment on a substrate including polydimethylsiloxane (PDMS); coating hydrophilic UV curing coating uniformly on the substrate; disposing the substrate into an oxygen-free environment; and exposing to an UV light to cure the hydrophilic UV curing coating. The method of modifying substrate surface may greatly enhance the hydrophilicity and the stability of the PDMS substrate.

Described herein are triboelectric energy generators that generally include a first flexible layer having a first electron donating material coated on at least a first surface and an electron accepting material coated over the first electron donating material, and a second flexible layer having a second electron donating material coated on at least a first surface. The first and second layers are positioned adjacent each other with their first surfaces facing inward toward each other and separated by a gap distance. An electric potential is generated upon movement between the first and second flexible layers, such as at least alternating contact and no-contact between the first and second flexible layers. The electron donating material may be provided by a particle-free conductive ink.

Ophthalmic devices coated with an active agent eluting coating are provided herein. Placement of the coated ophthalmic devices on the surface of eye results in modulation of cells responding to an immune modifying agent and reducing inflammation-related complications in the eye. Methods for treating ocular disorders are also provided herein. The disclosed subject matter is based, in part, on the discovery that ophthalmic devices coated with a cytokine eluting coating can shift early-stage macrophage polarization associated with alleviation of symptoms and causes of inflammatory ocular disorders.

The invention provides a filter fabric for providing anti pathogenic properties which has been coated with a composition comprising (a) 0.0001-99.9999% by weight of a compound of such as zinc pyrithione and (b) 0.0001-99.9999% by weight of an additional zinc salt selected from the group consisting of zinc acetate, zinc propionate, zinc oxalate, zinc benzoate, zinc gluconate, zinc ascorbate, zinc citrate, zinc lactate, zinc glycolate, zinc maleate, zinc fumarate, zinc polyacrylate and zinc polymaleate. The invention also provides a composition for imparting anti-viral properties to a breathable substrate material comprising two or more zinc salts selected from the group consisting of zinc acetate, zinc propionate, zinc oxalate, zinc benzoate, zinc gluconate, zinc ascorbate, zinc citrate, zinc lactate, zinc glycolate, zinc maleate, zinc fumarate, zinc EDTA, zinc glycinate, zinc polyacrylate, zinc polylactate, zinc polyglycolate and zinc polymaleate said zinc salts being present in effective amounts to impart anti-pathogenic properties.

In various embodiments, the present invention is directed to contact lenses that utilize a multilayer coating of alternating high RI materials, such as melanin or polydopamine (PDA) and other low RI materials to create tunable iridescent colors and contain melanin or similar materials that impart photoprotection due to their broadband UV-vis absorption spectrum and ability to quench radicals.

The invention relates to a process for the preparation of an oxygen barrier film having an oxygen barrier layer and a treated substrate, comprising the steps of: a) subjecting a polyolefin substrate to a surface treatment to obtain the treated substrate wherein the surface under the parts of the curves corresponding to the C—O, C—N and C═O groups is at least 10% based on the total surface under the curve as obtained by X-ray photoelectron spectroscopy (XPS), b) applying an aqueous or hydroalcoholic coating composition comprising 0.1 to 25 wt % of polyvinyl alcohol, 0.1 to 30 wt % of a metal alkoxide and optional silicate minerals on the treated substrate obtained by step a) and c) drying the coating composition to obtain the oxygen barrier layer resulting in the oxygen barrier film, wherein the amount of the optional silicate minerals in the coating composition is less than 10 parts by weight per 100 parts by weight of the polyvinyl alcohol in the coating composition.
