FexOy (Iron Oxide) Nanofibers


It is generally known that iron oxides mainly contain Fe2O3 and Fe3O4. Fe2O3 is stable in air, and possesses potential applications in adsorption, sensors, electrochemical catalysis, and other fields. On the other hand, Fe3O4 is a typical kind of magnetic material, which can be applied in magnetofluid as well as magnetic recording materials. Fe2O3 nanofibers with uniform structure can be easily prepared via an electrospinning technique followed by a calcination treatment (Fig. 3.6A). For example, Gao et al. prepared hollow a-Fe2O3 nanofibers via such a strategy and developed their potential in dye adsorption. Similarly, Nalbandian et al. found that electrospun Fe2O3 nanofibers possess promising prospects in heavy metal removal. Guo et al. studied the effect of the structure of electrospun Fe2O3 nanotubes on gas sensing; the results indicated that porous a-Fe2O3 nanotubes exhibited remarkably enhanced performance for acetone sensing over hollow a-Fe2O3 nanotubes. g-Fe2O3 nanofibers have also been successfully synthesized and their properties as acetone gas sensors have been found as well.

Single-Component Synthetic Polymer Nanofibers


Herein, we divide the synthetic polymers into several species. Among them, organic solvent-soluble polymers have been greatly developed, for example, electrospun polystyrene (PS) nanofibers have been prepared from different solvent systems (Fig. 3.5A). DMF, tetrahydrofuran, and their mixtures are the most commonly used solvents (Lin et al., 2010; Nitanan et al., 2012). Electrospinning of polyacrylonitrile (PAN) nanofibers also employs DMF as solvent (Fig. 3.5B), and they are a kind of excellent precursor for the fabrication of carbon nanofibers, which have been widely studied (Fen nessey and Farris, 2004; Gu et al., 2005). Polymethylmethacrylate (PMMA) is another familiar synthetic polymer; electrospun PMMA nanofibers as well as blended fibers have been developed for more than 10 years (Fig. 3.5C) (Ji et al., 2008; Carrizales et al., 2008).
