Abstract

The invention relates to mesotubes and nanotubes (hollow fibers) having an inner diameter of 10 nm-50 &mgr;m 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.
