| 摘要 |
The invention relates to composite fibers comprising ionically functionalized nanofibers or mesofibers and oppositely charged ionically functionalized particles which are applied to the surface of the fibers, a method for producing said composite fibers, and the use thereof. The nanofibers or mesofibers are composed of non-ionic polymers, carbon, polyelectrolytes, ionomers, ceramic materials, or metals. Production of the composite fibers according to the invention: polyelectrolytes and ionomers naturally have ionic groups on the surface; with the other fiber materials, ionic groups are produced, treated with a particle dispersion comprising oppositely charged, ionically functionalized particles, resulting in nanofibers or mesofibers, to the surface of which particles are applied. The ionically functionalized particles are preferably mesoparticles or nanoparticles and are selected from among non-ionic polymer particles, ionic polymer particles, ionomer particles, metal particles, carbon materials, pigments, magnetic particles, biological particles. The composite fibers according to the invention comprising ionically functionalized mesofibers or nanofibers and, on the surface thereof, oppositely charged ionically functionalized particles can be used for filter media and separation media, for finishing fabrics, releasing active substances, thermally insulating, protecting plants, in solar energy, sensor technology, and as thermoelectric materials, for example. |
