Abstract
The invention relates to mesotubes and nanotubes (hollow fibers) having an inner diameter of 10 nm-50 μm and to a method for the production thereof. The hollow fibers can be produced by coating degradable materials with non-degradable materials, whereby the degradable materials are destroyed by thermal methods, for instance. The hollow fibers are used in separation technology, catalysis, micro-electronics, medical technology, material technology or in the clothing industry.
Claims47
A fiber comprising a hollow fiber having an internal diameter of from 10 nm to 1 μm filled with a core material, its wall comprising one or more inorganic metal-containing compounds, polymers, metals or combinations thereof, wherein the core material has a mean separation from the inner wall of the hollow fiber of from 10 to 3000 nm.
A hollow fiber having an internal diameter of from 10 nm to 1 μm and an outer wall comprising one or more inorganic metal-containing compounds, polymers, metals or combinations thereof, said hollow fiber being prepared by coating, at least once, a degradable template fiber made by electrostatic spinning with one or more polymers, and subsequently degrading the degradable template fiber.
