Abstract:
Articles having crosslinked poly(vinyl alcohol) (PVA) and silica nanoparticle multilayer coatings are provided. More specifically, articles including a substrate, and a multilayer coating attached to the substrate are provided. The multilayer coating includes a first crosslinked poly(vinyl alcohol) (PVA) layer and a first silica layer. The first crosslinked PVA layer is an outermost layer of the multilayer coating. The first silica layer comprises a plurality of acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. The PVA and silica nanoparticle multilayer coatings can be used on a large variety of substrates and tend to be resistant to wet and dry abrasions, scratches, and impacts.
Abstract:
Tubular ceramic structures, e.g., anode components of tubular fuel cells, are manufactured by applying ceramic-forming composition to the external surface of the heat shrinkable polymeric tubular mandrel component of a rotating mandrel-spindle assembly, removing the spindle from the assembly after a predetermined thickness of tubular ceramic structure has been built up on the mandrel and thereafter heat shrinking the mandrel to cause the mandrel to separate from the tubular ceramic structure.
Abstract:
A method for producing a molded body having the following steps: a) providing a foil ply; b) applying a plastic molding compound in a predefined three-dimensional shape onto the foil ply by means of a three-dimensional printing method.
Abstract:
A polymer workpiece is described. The workpiece has an upper main surface, a lower main surface, an injection-mold separating surface and a flow attack edge surface. The flow attack edge surface is formed in the region between the injection-mold separating surface and the lower main surface as a planar surface with an angle α with respect to the injection-mold separating surface of 20° to 70°, and/or deviates by an amount a from 0.0 mm to 0.5 mm from the planar surface.
Abstract:
An all solution-processed deposition includes a non-water soluble, non-self-cracking film deposited by a solution process (e.g., spray, dip, spin coat, and the like), a water soluble, self-cracking film deposited by a solution process (e.g., spray, dip, spin coat, and the like), cracking of the film, and filling the cracks with a metal that is deposited in solution (e.g., by electroless disposition). A transparent substrate having a cracked water insoluble, non-self-cracking film surface coating includes a plurality of fissures therein extending to and exposing portions of the surface of the underlying transparent substrate is useful for producing a transparent conducting film.
Abstract:
Apparatus for forming and fibrillating a molten polymeric film into nanofibers consisting of a plurality of two-phase flow spinning nozzles arranged in a substantially liner array each nozzle into nanofibers including one or more first input orifices for a process gas; one or more second input orifices for a polymer melt; a flow channel including two or more channel walls and a monotonically decreasing flow area wherein the process gas and polymer melt are combined into a stratified two phase flow with the polymer melt formed into a film on one or more of the channel walls; and one or more channel exit openings, each exit opening including an edge at which the process gas reaches sonic velocity or less and where the edge is configured to fibrillate the polymeric film into a stream of nanofibers.
Abstract:
A disposable toothbrush having a toothpaste composition distributed over the bristles of the toothbrush without the use of metal graft initiators and catalysts, and in which the toothpaste and the flavoring is maintained for an extended period of time.
Abstract:
A medical apparatus, such as a cannula tip for a peripheral vein of a human body, wherein the medical apparatus includes a micro- or nano-structured superhydrophilic basecoat and a liquid topcoat, together comprising a superhydrophobic coating, which inhibit occlusion and/or catheter related bloodstream infection. The topcoat can further include compatible drugs and/or biomaterials to enhance compatibility and/or enhance durability of the topcoat.
Abstract:
A method of producing a printed image on a low-porous or non-porous medium. The method encompasses applying a pretreatment fluid including a liquid vehicle, at least one polymeric binder, and an associative thickener to the low-porous or non-porous medium; and applying an aqueous pigment ink composition to the pretreatment fluid applied to the low-porous or non-porous medium, wherein the pretreatment fluid has a viscosity of about 10 cps to about 1000 cps and a surface tension of about 16 dynes/cm to about 30 dynes/cm and the viscosity of the pretreatment fluid allows mixing of the pigment ink composition with the pretreatment fluid.
