Abstract:
The invention relates to textile fibers at least partially covered with a nanometric-sized semiconducting material having photocatalytic properties for degrading chemical compounds, in particular chemical or biological agents, wherein said semiconducting material is in the form of nanostructure or nanocomposites with a one-dimensional morphology. The textile fibers can be used for application in the military, medical, and civilian domains, etc. The curves 60 and 62 respectively show the photocatalytic degradation of organic compounds at the surface of textile fibers covered with nanostructures or nanocomposites having a one-dimensional morphology according to the invention, and nanoparticles having a granular morphology according to the prior art. The nanostructures are nanocomposites of the invention 60 are more efficient.
