摘要： A method of preparing hexagonal boron nitride (h-BN) fibers includes mixing polyvinylpyrrolidone (PVP) and boron oxide (B2O3) to form a polymer precursor or mixing PVP and ammonia borane (BH3NH3) to form the polymer precursor. The method includes forcespinning the polymer precursor to form fibers of the polymer precursor, curing the fibers to form polymer fibers, and pyrolyzing the polymer fibers to form the h-BN fibers.

摘要： The invention shows a spin-up device (11, 51) and a method for spinning up a spinning device (1, 101) for the continuous extrusion of molded bodies (3) from a spinning solution (6), containing a solvent and cellulose dissolved in the solvent, wherein the molded bodies are extruded from the spinning solution (6) through spinnerets (7) of the spinning device (1, 101) in the form of a loose spinning curtain (2), the molded bodies (3) of the loose spinning curtain (2) are combined into a molded body bundle (4) after the extrusion, and the molded body bundle (4) is, in a further step, fed to a draw-off member (10) of the spinning device (1, 101) in order to start a continuous extrusion of the molded bodies (3). In order to make the spin-up method simpler in terms of process technology and more reproducible, it is proposed to increase the tensile strength of at least some areas of the molded bodies (3) of the loose spinning curtain (2) after their extrusion and before combining them into a molded body bundle (4).

摘要： The present invention relates to a process for the preparation of polyolefin fibers having mean fiber diameters of less than 5000 nm, comprising the steps of: a) preparing a polyolefin solution in a solvent, b) placing said polyolefin solution in a fiber producing device comprising a body configured to receive said polyolefin solution, said body comprising one or more openings, and c) rotating the fiber producing device, wherein rotation of the fiber producing device causes the polyolefin solution to be passed through said one or more openings to produce polyolefin fibers having mean fiber diameters of less than 5000 nm, wherein said polyolefin is selected from the group comprising polyethylene polymers and copolymers having a weight average molecular weight Mw of at least 40 000 daltons, and polypropylene polymers and copolymers, having a weight average molecular weight Mw of at least 120 000 daltons; wherein said fiber producing device is rotated at a speed of at least 10 000 revolutions per minutes (RPM). The invention also relates to said polyolefin fibers, and to articles comprising said fibers.

摘要： A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.
