An apparatus for roll-to-roll nanomaterial dispersion papermaking includes a suction pressure for consolidating nanomaterials on a fluid permeable filter in one region of the filter and an opposite pressure region or regions for separating a mat of the consolidated nanomaterials and transferring the mat to a transfer roller. A transfer roller may have a suction pressure within the transfer roller to help transfer the mat from the filter to the transfer roller, for example. An inlet port distributes nanomaterials using row and zone inlets, for example.

A method for manufacturing a continuous sheet of CNTs, comprising: in a container (41) filled with a liquid solution (42) comprising CNTs at certain concentration, submerging a vacuum tank (43) having a lower surface forming a grillage; moving an elongated filtering membrane (44) along the lower surface of the vacuum tank (43) while vacuum is applied on the elongated filtering membrane (44) in such a way that in the surface of the filtering membrane (44) opposed to the surface in contact with the lower surface of the vacuum tank (43) CNTs are deposited forming a continuous sheet of CNTs (45) of constant thickness; taking the filtering membrane (44) together with the continuous sheet of CNTs (45) out of the container (41); washing the continuous sheet of CNTs (55) disposed on the filtering membrane or on a support element (54) in a second container (51) filled with cleaning solution (52); taking the continuous sheet of CNTs (55) together with the filtering membrane or the support element (54) out of the second container (51); separating the continuous sheet of CNTs (55) from the filtering membrane or the support element (54); drying the continuous sheet of CNTs (55) by applying the method for increasing the thickness of a sheet of CNTs.

A film-stretching apparatus in accordance with an embodiment of the present invention includes a stretching furnace which is divided into a plurality of air amount control zones. In a case where the number of the plurality of air amount control zones is seven, a total amount of air to be discharged from, out of the plurality of air amount control zones, three air amount control zones which are located on an entrance side of the stretching furnace is controlled so as to be larger than a total amount of air to be discharged from, out of the plurality of air amount control zones, three air amount control zones which are located on an exit side of the stretching furnace.

Disclosed are polyimide blends and methods of making and using same. The disclosed polyimide blends are prepared by first blending an ionic polymer and a poly(amic acid) to form a poly(amic acid) precursor, followed by cyclization. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Provided is a compression bar apparatus for applying pressure to desired areas of a thin film composite (TFC) membrane, such as spiral wound TFC membranes and elements, including membranes and elements used for nanofiltration, reverse osmosis or forward osmosis to purify water, such as tap water, seawater, and brackish water. Application of pressure to a spiral wound element by the apparatus produces a membrane with increased sealant penetration, reduced osmotic blistering, and minimal damage to the active area of the membrane. Also provided are methods of using the apparatus.

The present invention relates to a composite separation membrane including a graphene oxide coating layer. The composite separation membrane of the present invention has both high carbon dioxide permeability and high selectivity for carbon dioxide over nitrogen, hydrogen or methane gas, is free of surface defects, and exhibits remarkably increased selectivity for carbon dioxide over other gases (hydrogen, nitrogen, methane, etc.) without any change in carbon dioxide permeability, particularly even when exposed to water. Due to these advantages, the composite separation membrane of the present invention can be applied to industrial fields involving carbon dioxide separation and recovery processes. The present invention also relates to a method for manufacturing the composite separation membrane.

Described are porous membrane products that contain two or more membrane layers bonded together at a portion of the area of the membranes, methods and system for preparing the porous membrane products, and methods of using the porous membrane products.

The present disclosure relates to improved collapsible blood containers comprising reinforced silicone for use in Oxygen Reduction Disposable kits (ORDKit), devices and methods. The improved collapsible blood containers and methods for the collection of blood and blood components provide for improved burst, tear, and puncture resistance.
