A composite structure is provided that includes a polymer layer and an auxetic material layer disposed within or partially within the polymer layer. The auxetic material layer provides increased conductivity and elastomeric reinforcement to the polymer layer.

The present disclosure describes covers for electronic devices, electronic devices, and methods of making covers for the electronic devices. In an example, a cover for an electronic device can comprise: a rigid substrate; a high refraction polymeric film adherable on the rigid substrate; a semitransparent polymeric film adherable on the high refraction polymeric film, wherein the high refraction polymeric film comprises: polyacrylic, polycarbonate, cyclic olefin copolymer, or combinations thereof, and high refractive nanoparticles, and wherein the semi-transparent polymeric film comprises: polyester, polyacrylic, polycarbonate, polyvinyl chloride, silicone rubber, or combinations thereof, and at least one colorant.

A laminated structure includes a first member, a second member that faces the first member, and a filling member that is disposed between the first member and the second member, and a difference between a value of a relative permittivity of a member with a largest relative permittivity and a value of a relative permittivity of a member with a lowest relative permittivity among the first member, the second member and the filling member is 1.0 or less.

The present invention discloses a backplate and a display panel. The backplate includes a substrate layer. Material of the substrate layer includes a doped material. The doped material includes thermally conductive particles.

The present disclosure relates to a breathable layered flexible material comprising at least one polyvinyl chloride (PVC) porous layer or a plurality of PVC porous layers and a support layer. The the pores of the PVC porous layer or plurality of PVC porous layers are obtainable by water evaporation of a water-in-oil PVC emulsion. The pores extend from the PVC layer to the support layer providing the material breathability. The disclosure also relates to a method for preparing the breathable layered flexible material. Upholsteries, in particular car upholsteries, comprising the breathable layered flexible material are also disclosed.

The present invention refers to a composite material that comprises carbon fiber or sheet made from polyacrylonitrile (PAN) or lignin being indicated for the manufacture of several articles such as high resistance pressure cylinder. Said material presents several advantages such as, for example, to provide improved screening to the articles that comprise it. The referred composite comprises: a first inner layer of polytetrafluorethylene, covered by a second layer of high-density polyethylene, adhered to a third layer of composite containing carbon fiber or sheet made from polyacrylonitrile (PAN) or lignin immersed in cured epoxy resin from a polymeric matrix and a hardener; and a fourth outer layer of composite, comprising aramid fiber impregnated with a dilating fluid and cured epoxy resin from a polymeric matrix and a hardener.

A protective fabric which includes at least one structural layer and a ceramic composite material layer fixed to the at least one structural layer, is provided. The structural layer can include a non-woven material made from or containing synthetic fibers. The ceramic composite material layer is formed of ceramic composite material powder which includes a ceramic carrier, and iron-silver crystals containing zero-valent iron and zero-valent silver supported on the ceramic carrier. The protective fabric is effective for removing VOCs, suppressing bacterial growth, and filtering or inactivating virus, such as SARS-CoV-2 virus. Protective products or articles incorporating the protective fabric are also provided.

An electroceutical system integrated into an article of personal protective equipment (PPE) like a face mask. The system consists of an electrochemical cell consisting of an anodic zone capable of serving as an anode, a cathodic zone capable of serving as a cathode and, optionally, a selectively conductive switch zone electrically couplable to and separating the anodic and cathodic zones and serving to switch on and off current flow between the anodic and cathodic zones.

A filtration article for using in personal protective equipment (“PPE”) that includes one or more layers. The article has an external side for facing side the environment and an internal side for facing the body of a user. The article is air permeable but has a porosity sufficient to entrap and thereby filter selected infectious agents (IAs). The one or more layers comprise structures providing two or more of the following functional features selected from the group of: (1) a structure with oligodynamic materials for inactivating the selected IAs; (2) a structure of carbon fibers or particles for moisture management and/or conductive cooling; (3) a knit or woven structure having yarns in a denier gradient that causes wicking of water from the internal side of the mask toward the external side; (4) an energized or energizable structure that subjects entrapped IAs to current, charged particles, electrostatic discharge, resistive heating, IR heating and/or disruptive electromagnetic energy; and (5) a hydrophobic structure forming an external surface of the external side for repelling droplets and other moisture from absorbing into the surface.
