In this work we present a new approach to produce a nanocomposite made of non-woven silicate glass fibers containing silver nanoparticles. The process first involves the synthesis of pellets of a soda-lime silicate glass containing silver nanoparticles with varying concentration (5 and 10 wt.%). These pellets were used as a precursor for the production of the glass fibers using the laser spinning technique. The fibers exhibited diameters ranging from tens of nanometers up to several micrometers and silver nanoparticles are uniformly distributed through their whole volume. One of the most outstanding results of this new approach is that the metallic nanoparticles were not significantly agglomerated, the average particles size is still lower than 50 nm. This is the first time that glass nanofibers containing silver nanoparticles were obtained following a process different from electrospinning of a sol-gel, thus avoiding the limitations of this method and opening up a new route to composite nanomaterials.
