PAN fibers with nanoprecipitated Ag and Au for use in textronics

Silver and gold nanoparticles have been linked with the structure of polyacrylonitrile (PAN) fibers as a result of a synthesis. The nanoparticles were formed in the dimethylformamide (DMF) solution, which is uncommon for their synthesis, but is a typical solvent for polyacrylonitrile. The examination of metallic nanoparticles doped fibers showed the presence of these particles in the samples. Analysis of Energy Dispersive X-ray Spectrometry (EDX) results showed that silver content in the fibers was the same as in the precursors of metal ions. The amount of silver in the fibers was significantly greater than the amount of gold in the corresponding sample. The Dynamic Light Scattering Method (DLS) and Visible and Ultraviolet Spectroscopy (UV-Vis) analyses indicated a difference between the sizes of metallic nanoparticles. The obtained composite polyacrylonitrile fibers doped with silver and gold nanoparticles were characterized by high flexibility and reduced electromagnetic radiation. The authors are convinced that the results obtained during the research will considerably contribute to the development of textronics discipline.
