Immobilization of Metal Nanoparticles on Ultrafine Electrospun Polymer Fibers

摘要

Metal nanoparticles are of continuing interest because of their unusual properties compared to the bulk metal that are applicable to novel electrical, optical, magnetic and catalytic, chemical/biochemical sensing technologies. In some applications, metal nanoparticles are immobilized on various substrates. Microfibers such as natural porous cellulose fibers and modified commercial polyacrylonitrile fibers, which have large specific surface areas, were reported to be used as substrates for the absorption of different metal ions and in-situ synthesis of metal nanoparticles.
