A filament production device, in particular a filament reaction-spinning production device, comprising at least one spinning nozzle unit, which is provided for producing at least one filament formed as a hollow fibre membrane from at least one polymer solution, and comprising a polymerisation unit, which is provided for initiating a polymerisation of the polymer solution, wherein the polymerisation unit is provided for initiating the polymerisation at least partially within the spinning nozzle unit.

A method is disclosed including causing a preform 1 that is softened to pass from an inner side of a container-shaped member 10 having a shape of a container having a through hole 12 at a bottom thereof through the through hole 12. The preform 1 includes a resin. At least an inner surface 10i of the container-shaped member 10 is formed of a material including glass, a heat-resistant resin, or aluminum as a main component. In one embodiment of the present invention, the preform 1 is heated while the preform 1 and a metallic member 20 in which the container-shaped member 10 is disposed are not in direct contact with each other, and the preform 1 softened thereby is caused to pass through the through hole 12 and then through a tubular portion 26 of the metallic member 20 to shape the preform 1 into a fibrous shape.

The preset invention provides an electrode structure for a lithium ion battery comprising an electrode selected from a cathode including a lithium-based material or an anode including a conductive material, and a melt-convertible encapsulation layer covering at least one surface layer of the electrode. The melt-convertible encapsulation layer comprises a network of nanofibers having the diameter ranging approximately from 100 to 300 nm and polymer microspheres embedded in and coated on the nanofibrous network, wherein the ratio of the diameter of the polymer microspheres to the diameter of the nanofiber is over 30. The polymer microspheres melt to form a dielectric coating of the electrode so as to prevent fire or thermal runaway at a temperature approximately from 100 to 200° C.

Light-permeable multilayer composite film made of plastic as the surface coating of an article, wherein the composite film comprises at least one outer, at least partially light-permeable top layer optionally provided with a lacquer and at least one further layer arranged on the back of the top layer, wherein arranged on the back side of the top layer is at least one sheetlike, optically active textile layer, preferably a textile layer comprising threads made of polyethylene terephthalate (PET) and/or made of polyvinylidene fluoride (PVDF), wherein the textile layer has light-transmitting, light-refracting and light-reflecting properties or a combination thereof and the transmission, refraction and reflection properties are such that illumination of the textile layer, in particular back side illumination of the textile layer, results in preferably uniformized light transmission through the top layer.

Some aspects of the disclosure relate to composite materials and cultivation systems with particular utility for use in aquaculture, for example cultivating various species of seaweed. The systems comprise at least one highly tortuous and often micro-fibrous material and at least one material having low tortuosity. These systems may be configured in a variety of shapes and associated with a number of different structures. Some of these composite materials and cultivation systems may be used in both direct and indirect seeding of macroalgae plants such as seaweed.

A sliding seismic isolation device includes a structure fixation plate having a first sliding surface and a metallic slider having a second sliding surface contacting the first sliding surface. A friction member composed of a single-layer fabric is attached to the first sliding surface, the second sliding surface, or both of the first sliding surface and the second sliding surface. One of a warp and a weft is formed of multiple plied yarns into which high-strength fibers and PTFE fibers are twisted together and the other of the warp and the weft is formed of multiple high-strength fibers in the single-layer fabric. The single-layer fabric has a twill weave and is woven such that the plied yarns of the one forming the single-layer fabric are exposed at a surface opposite from the attachment side of the friction member more than the high-strength fibers of the other forming the single-layer fabric.

The invention provides an enhanced electrospun film made from polyvinylidene fluoride (PVDF) and at least one low-melting-point polymer in a ratio of 99.9:0.1-90:10 by weight, and the low-melting-point polymer having a melting point lower than the polyvinylidene fluoride and a softening point in the range of 110-140 C°. The enhanced electrospun film exhibits excellent mechanical properties, higher moisture permeability and hydrostatic pressure resistance. The invention further provides a method for manufacturing the enhanced PVDF electrospun film, and use of the enhanced PVDF electrospun film in preparing a waterproof and moisture permeable product.
