The packaging structure, for example, an edge protector, a corner board, etc., may generally include a first ply having a first width, a second ply having a second width, and a third ply having a third width wider than the first width and the second width. The second ply may be wrapped around at least one end of the first ply, and the third ply may be wrapped around the first ply and the second ply. The third ply may overlap at a portion (e.g., an intermediate portion, an apex, etc.) of the packaging structure.

Functionalized textile materials are provided. At least a portion of a textile surface in includes a ceramic material, such as a binderless porous structured ceramic, and optionally, one or more functional layer is applied, resulting in a textile material with one or more desirable functional properties, such as hydrophilicity, hydrophobicity, flame retardancy, photocatalysis, anti-fouling, and/or deodorant properties.

Multifunctional surfacing materials for use in composite structures are disclosed. According to one embodiment, the surfacing material includes (a) a stiffening layer, (b) a curable resin layer, (c) a conductive layer, and (d) a nonwoven layer, wherein the stiffening layer (a) and the nonwoven layer (d) are outermost layers, and the exposed surfaces of the outermost layers are substantially tack-free at room temperature (20° C. to 25° C.). The conductive layer may be interposed between the curable resin layer and the stiffening layer or embedded in the curable resin layer. According to another embodiment, the surfacing material includes a fluid barrier film between two curable resin layers. The surfacing materials may be in the form of a continuous or elongated tape that is suitable for automated placement.

Systems and methods for providing a buoyant portable device. The buoyant portable device, comprising a frame and layers disposed in the frame. The layers comprise a first layer spaced apart from a stack of densely packed second layers such that a hollow cavity filled with air resides between the first layer and second layers. The hollow cavity has a size/shape providing an overall density of the mobile device that is below a density of a liquid that the mobile device displaces when the mobile device is disposed in the liquid. The second layers comprise an electronic layer residing adjacent to a cover/display layer. The cover/display layer is configured to allow a user to interact with electronic components of the electronic layer and has an overall weight less than a combined weight of the frame and at least the first layer of the plurality of layers.

An encapsulation film, an organic electronic device comprising the same, and a method for manufacturing an organic electronic device using the same are provided. The encapsulation film has excellent reliability that allows forming a structure capable of blocking moisture or oxygen flowing into an organic electronic device from the outside, absorbs and disperses the stress according to panel bending caused by CTE mismatch, and overcomes the performance decrease due to reliability degradation, while preventing generation of bright spots in the organic electronic device.

A multi-layered material with low thickness is provided, having properties of thermal and electric insulation, flame retardant capacity and high mechanical strength, useful for the manufacture of personal protective equipment and more in general of work items for the protection against arc flash effects. The material provides a high grade of protection against arc flash with good flexibility and comfort for the wearer, who is thus protected without being hindered in movements.

A nonwoven web obtained by electrospinning, suitable for the filtration of nano- and/or submicron aerosols, including a multiplicity of fibers of composition C1, the composition C1 including at least 50% by weight of at least one polymer P1 based on the repeat unit resulting from vinylidene fluoride (VDF), the fibers of composition C1 having a degree of crystallinity in polar phase(s), preferentially in solely beta phase, of at least 65% by weight, with respect to their total weight. Also, a process for the manufacture of the web, to a membrane including the web and also to a process for the washing/sterilization of the web or of the membrane.

An antiviral mask and antiviral filter include a thin breathable, microporous polymeric membrane. That membrane may include a plurality of pores functionalized with a proteolytic enzyme, an antibody or a combination thereof. The antiviral mask and antiviral filter may also include a coating of graphene oxide, lignin sulfonate or a combination thereof and/or a fluorescent virus tagging agent.
