UV-VIS ANALYSIS OF COMPOSITE POLYACRYLONITRILE/IRON OXIDE NANOPARTICLES THIN FIBROUS MATS

Iron oxide nanoparticles have a wide range of properties and a lot of applications in today nano-world. They can be used as: catalyst system [1], biomaterials for the tissue engineering [2], good base for magnetic nanoparticles – to locate hyperthermia, membranes for water purification or thermal energy storage. Poliacrylonitrile, although thermoplastic, is also rigid and brittle and used in manufacturing of synthetic fibers. The most useful applications of nanofibers reinforced by the Fe2O3 nanoparticles are in catalyst systems. Space between nanofibers is so small that all impurities are stopped and removed. In water treatment plants, chrome is the main element to be removed, because of its noxiousness to humans. The aim of this study was to fabricate composite nanofibers reinforced by the Fe2O3 nanoparticles with a polymer matrix of polyacrylonitrile (PAN) by the method of the solution electrospinning. After the production, morphology and structure were analyzed on scanning electron microscope; optical properties were analyzed by UV-VIS spectroscopy.
