A non-wicking underlayment board and methods for forming the same. The non-wicking underlayment board includes a foam core formed of closed cell foam with reinforcement layers encapsulated within the foam core. Outer facings formed of mineral coated nonwoven fibers are positioned on opposite faces of the non-wicking underlayment panel. The non-wicking underlayment board is useful for efficient and cost effective installation of barriers and surfaces in water-resistant and waterproof environments.

Various embodiments provide multi-layered self-healing materials, capable of repairing puncture damage. The multi-layered self-healing materials, capable of repairing puncture damage of the various embodiments may be constructed by sandwiching a reactive (e.g., oxygen sensitive) liquid monomer formulation between two solid polymer panels, such as a polymer panel of Barex 210 IN (PBG) serving as the front layer panel and a polymer panel of Surlyn® 8940 serving as the back layer panel. The various embodiments may provide methods to produce multi-layered healing polymer systems. The various embodiments may provide a two-tier, self-healing material system that provides a non-intrusive capability to mitigate mid to high velocity impact damage in structures.

The invention relates to a method for the production of a laminated core comprising a stack of metallic plates, in which: —a metallic sheet (2, 3) is chosen, having a first main face (4, 8) and a second main face (6, 9) which are coated with a sub-layer comprising at least one material selected from epoxides and polyepoxides, —a layer (12, 20) with a thickness of less than 500 μm of a precursor composition selected from partly epoxides and at least partly cross-linked polyepoxides is placed in contact with said sub-layer, —a layer (16, 22) with a thickness of less than 500 μm of a curing composition comprising at least one crosslinking agent is placed in contact with said sub-layer, —said metallic sheet is punched, —the metallic plates are then superposed to each other.

A method of manufacturing a two-layer nanocellulose composite sheet is provided. The two-layer nanocellulose composite sheet is comprised of a moisturized nanocellulose material and a fabric. The method includes the steps of dispersing a diluted nanocellulose suspension onto a fabric, and partially drying the diluted nanocellulose suspension until the diluted nanocellulose suspension is transformed to the moisturized nanocellulose material bonded to the fabric. Thereby, a surface of the moisturized nanocellulose material is bonded by mechanical adhesion to a surface of the fabric. The nanocellulose composite sheet manufactured by this method has contour conformability, excellent skin-adhesion, and high capacity for moisture retention and release, and is ideal for dermatological treatments. An apparatus for manufacturing the nanocellulose composite sheet is also provided.

A display device comprises a display area including a corner portion, a display panel including a non-display area located around the display area, and a cover window disposed on the display panel. The display panel includes a flexible substrate, and a crack propagation prevention pattern including a first organic layer disposed on the flexible substrate and directly contacting the flexible substrate. The intersecting point of a bending line overlaps with the crack propagation prevention pattern in the a thickness direction. In addition, the display device further includes alignment marks which overlap with the bending line.

A back film for a display device and the display device are provided in the present disclosure. The back film includes an opening region and a non-opening region, and the back film includes a first flexible material layer and a polyimide layer laminated one on another. An opening penetrating through the first flexible material layer and the second flexible material layer is formed in the back film, and a region corresponding to the opening is the opening region. The back film further includes a protection member covering the camera region.
