A method of manufacturing a supported copper product is disclosed. The method includes: providing a thin copper foil and a poly-based film containing polyimide and polytetrafluoroethylene, the poly-based film having an adhesive applied to a surface of the poly-based film; thermally treating the thin copper foil and the poly-based film along their respective lengths, the thermal treatment being adjustable to vary an amount of heat applied to the thin copper foil and the poly-based film; and attaching the thermally treated thin copper foil and the thermally treated poly-based film using the adhesive applied at the surface of the poly-based film.

A method for making a bonded article, wherein a thin glass substrate is bonded on a support substrate in the absence of any interlayer by an electrostatic adhesion process with the assistance of external pressure, the pressure is applied constantly or stepwise during the adhesion process by use of a tool such as a roll or a wheel or other movable device with curved surface. The bonded article has no defects, e.g. bubbles or inclusions, in the bonded interface, which benefits transportation of the thin glass substrate and its post-processing as well. Such defect-free bonded article is also disclosed. Pressure supported electrostatic adhesion, initiated by electrostatic charges adhesion of a two members, e.g. a substrate member and a support member, is enabled to minimize, prevent and exclude defects, distortion between the adhered surfaces.

Acoustic mediums are disclosed herein. The acoustic mediums can include a plurality of layers. The layers of the acoustic mediums can include fibrous acoustic materials that are entangled throughout the layer. In certain instances, the layers of the acoustic medium can include first portion of acoustic materials disposed along a first plane, and a second portion of acoustic materials disposed along a second plane. Methods of fabricating multi-layer acoustic mediums are also disclosed.

A system and method for producing a heat-sealable composite liquid impervious, moisture-eliminating membrane with a metallic antimicrobial surface treatment including a compatibilized thermoplastic laminate structure, an integral inductive-welding element, and a metallic antimicrobial surface treatment. The method is provided with at least one scrim, a film exudate, a quantity of primary adhesive, at least one susceptor, and a quantity of flocking material, wherein the scrim, film exudate, and flocking material are composed of a compatibilized thermoplastic compound. The method is further provided with an optional metallic slurry, defining a thermoplastic-particulate emulsion configured to coat and embed into a subjected membrane section and fibrous materials when exposed to heat. The method is further expanded to apply to extant installations of similar membrane sections, enabling to post-manufacture surface treatment of a surface with the metallic slurry to confer manifold antimicrobial benefits to said surface.

A method of forming a composite sheet material, the method comprises energising a pair of electrodes to apply an electrostatic charge to a bed of fibres located therebetween thereby orienting at least some of the fibres to be substantially orthogonal to the electrodes and sandwiching at least some of the oriented fibres between a first sheet and a second sheet. The first sheet may be subsequently removed. A third sheet may be used to sandwich the fibres between the second sheet and the third sheet. Apparatus (100) is disclosed for carrying out the method.
