Some embodiments comprise membranes comprising a first layer comprising a porous graphene-based material; a second layer comprising a porous graphene-based material; a channel positioned between the first layer and the second layer, wherein the channel has a tunable channel diameter; and at least one spacer substance positioned in the channel, wherein the spacer substance is responsive to the environmental stimulus. In some cases, the membranes have more than two layers of porous graphene-based material. Permeability of a membrane can be altered by exposing the membrane to an environmental stimulus. Membranes can be used in methods of water filtration, immune-isolation, timed drug release (e.g., sustained or delayed release), hemodialysis, or hemofiltration.

A transaction instrument comprising a metal-filled biodegradable polymer. The biodegradable polymer is a plant-based polymer, a protein-based polymer, or a combination thereof. The metal of the blended composite of metal and biodegradable polymer is a heavy-gravity compound. The transaction instrument is biodegradable in whole or in part. A method(s) for making a transaction instrument comprising a blended composite of metal and a biodegradable polymer is also provided.

A panel having side edges for connection to a further panel in order to cover a surface of a room, includes an upper side, an underside, and at least four side edges. The panel has a multilayer structure including an elastic base layer, made entirely or predominantly of an elastically adjusted polyurethane, and above the base layer a top layer which compared to the base layer is less elastic. The top layer is pressed via an adhesive layer with the base layer to form the multi-layer structure.

A sheet for heat bonding, having a pre-sintering layer that becomes a sintered layer by being heated, and an adhesion layer.

An interlayer structure having a cellulose ester layer for use in structural laminates is described herein. The cellulose ester layer provides rigidity and support to multilayer interlayers comprising an array of different layers. Due to the diverse properties of the cellulose ester layers, the present interlayers can be useful in producing structural laminates having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications.

The invention relates to a method for producing a bobbin and a bobbin. The bobbin includes a plurality of windings of a continuous laminated sheet having at least one layer of alkaloids containing material and at least one layer of a first protective material. The at least one layer of alkaloids containing material and the at least one layer of a first protective material define an adhesion surface between them. The first protective material is selected from polypropylene, polyethylene, polytetrafluoroethylene, polyester, or paper.

A multilayer film is provided that includes a) a barrier layer including a thermoplastic polyester elastomer or a polyamide copolymer; b) an intermediate layer provided on the barrier layer and including a maleic anhydride (MAH)-grafted polyolefin and an ?-olefin copolymer; and c) an adhesive layer provided on the intermediate layer and including a thermoplastic polyester elastomer or a polyamide copolymer. The multilayer film enables production of gas-tight multilayer laminates which exhibit an excellent peel resistance combined with a low weight and/or thickness. Further, a multilayer laminate and an inflatable airbag that include a fabric layer adhered to the multilayer film, as well as methods of manufacturing are described.

An antiglare film in which occurrence of screen scintillation and white muddiness can be sufficiently prevented at a high level while maintaining hard coating properties and antiglare properties, and excellent display images with a high contrast can be provided. The antiglare film includes a light-transmitting substrate; and an antiglare layer having a surface roughness on at least one surface of the light-transmitting substrate, wherein the antiglare layer contains an aggregate composed of two or more types of fine particles, and the aggregate forms a projection of the surface of the antiglare layer to form a surface roughness on the antiglare layer.
