A supported elastomeric foam (100) includes an elastomeric matrix (102) formed of an elastomer and including a reinforcement region (104) and a foamed region (106). The foamed region includes gas filled cells (108) in the elastomer, and the reinforcement region includes a porous layer (204) having an interconnected network of pores at least partially imbibed with the elastomer. The foam can include an adhesive at a surface of the foam. A compressible seal (802) including a compressible body, which can be elastomeric foam, can also include a pattern of discontinuous adhesive regions about which the compressible body can deform to form a sea. The supported elastomeric foam can form a gas tight seal in an interface when placed under minimal compression.

The objective of the present invention is to provide a porous support that is unlikely to curl (the incidence of MD curling is low). This porous support has a polymer porous layer on one surface of a nonwoven cloth layer, the nonwoven cloth layer having an MD bend stiffness of 1.2 to 2.1 g.Math.cm.sup.2/cm, and an MD bend recovery of 0.3 to 0.6 g.Math.cm/cm. The nonwoven cloth layer is impregnated with a polymer that is the material for forming the polymer porous layer, the impregnation ratio of the polymer impregnated in the nonwoven cloth layer being 25 to 34% by weight of the total weight of the polymer in the polymer porous layer and the polymer impregnated in the nonwoven cloth layer.

Multilayer polymer sheets are provided, as well as related methods, systems, and appliances.

The microwave packaging material can comprise a film at least partially secured to a substrate by a pattern of adhesive. A plurality of closed cells can extend between the film and the substrate, each closed cell of the plurality of closed cells can be at least partially defined by the pattern of adhesive, and each of the closed cells can be configured to expand during heating to form respective expanded cells. The microwave packaging material further can comprise a bonded region extending along at least a portion of the microwave packaging material. The film can be secured to the substrate along the bonded region, and the bonded region can be for forming at least one recess among the expanded cells and can be for extending along the food item when the microwave packaging material is heated.

A gas barrier composite film is provided. The gas barrier composite film includes a substrate layer; a functional layer disposed on one or two sides of the substrate layer, wherein the functional layer includes a first copolymer of p-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid, or a second copolymer of acrylic acid and vinylidene dichloride, and an inorganic stack layer disposed on the functional layer.

##STR00001##

wherein for each polymer A and B, t1, and w1 independently represent 0 or 1 and v1 represents 0, 1 or 2. A method of forming the reinforcement sheet is also disclosed, in addition to a method for forming an article comprising a laminate of the reinforcement sheets and the article comprising such a laminate. The repeat unit may be ether-ether-ketone.

Provided are a thermoplastic polymer capable of reducing a dielectric dissipation factor in high frequency bands and a film thereof. The thermoplastic liquid crystal polymer includes repeating units represented by the following formulae (I), (II), (III) and (IV), in which a molar ratio of a total amount of the repeating units represented by formulae (I) and (II) to a total amount of all the repeating units in the thermoplastic liquid crystal polymer is 50 to 90 mol %, and a molar ratio of the repeating unit represented by formula (III) to the repeating unit represented by formula (IV) is the former/the latter=23/77 to 77/23.

Membranes comprising graphene oxide sheets and associated filter media and methods are provided. In some embodiments, a membrane may comprise graphene oxide sheets that have undergone one or more chemical treatments. The chemical treatment(s) may impart beneficial properties to the membrane, such as a relatively small d-spacing, compatibility with a broad range of environments, physical stability, and charge neutrality. For example, the graphene oxide sheets may undergo one or more chemical treatments that form chemical linkages between at least a portion of the graphene oxide sheets in the membrane. Such chemical linkages may impart a small d-spacing, broad compatibility, and/or allow relatively thick membranes to be formed. In certain embodiments, the graphene oxide sheets may undergo one or more chemical treatment that imparts relative charge neutrality to the membrane by altering the ionizability of certain functional groups. Graphene oxide membranes, described herein, can be used for a wide range applications.

Provided is a mold release film capable of transferring a concave-convex structure to the surface of an adhesive film.

A display device according to an embodiment includes a display panel and a protection layer that is disposed on the display panel, wherein the protection layer includes: a first protection layer; a metal layer that overlaps the first protection layer and includes a hole; and an adhesive layer disposed between the first protection layer and the metal layer. The adhesive layer includes a first area disposed between the first protection layer and the metal layer, and a second area and a third area that are disposed in the hole, wherein a peeling strength of the second area and a peeling strength of the third area are different from each other.
