A decorative sheet for vacuum forming is difficult to peel off during vacuum forming between a first vinyl chloride-based resin layer and a second vinyl chloride-based resin layer and can give a design of various colors. This decorative sheet for vacuum forming includes: a first vinyl chloride-based resin layer containing a vinyl chloride-based resin and a coloring agent; and a second vinyl chloride-based resin layer which is laminated on the first vinyl chloride-based resin layer, contains a vinyl chloride-based resin, and is transparent, wherein the content of titanium oxide particles of the coloring agent is less than 1 part by mass, the first vinyl chloride-based resin layer contains inorganic particles, and at least some of the inorganic particles are calcium carbonate particles.

The present disclosure provides a resin composition containing a bio-polyethylene resin (A), an ethylene-vinyl alcohol copolymer (B), and an alkali metal salt (C), wherein the content of the alkali metal salt (C) is 10 ppm to 1500 ppm, in terms of metal, with respect to the weight of the ethylene-vinyl alcohol copolymer (B). With this resin composition, gel formation and a reduction in transparency during molding are suppressed, and a molded product having an excellent appearance can thus be obtained.

An example electronic device includes a transparent cover; and a flexible display coupled to the cover. The cover may include a first layer including glass; a second layer positioned between the first layer and the flexible display; and a third layer positioned between the first layer and the second layer. The third layer includes a pattern overlapping a folding part of the flexible display and including a plurality of grooves formed in a bonding surface with the second layer, and has a hardness greater than that of the second layer.

A non-woven protective clothing against blood and viruses, which is composed from: a non-woven fabric layer, which has two surfaces; and a high waterproof moisture-permeable layer, which is a porous film that is laminated to one of the surfaces of the non-woven fabric layer; and an elastic pore filling layer, which is a hydrophilic polyurethane. The elastic pore filling layer is coated or printed onto the surface of the high waterproof moisture-permeable layer, and the thickness of the elastic pore filling layer is thinner than that of the high waterproof moisture-permeable layer. The synthetic blood permeability of the non-woven protective clothing against blood and viruses can resist a pressure of 2.0 psi for one minute, and the Phi-X174 bacteriophage penetrability thereof can resist a pressure of 2.0 psi for one minute.

A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m.sup.2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.
