“…The improved mechanical and electrical properties of above aligned nanotube/polymer composite have been realized through the direct use of nanotube arrays, sheets, and fibers. In the case of other approaches to align nanotubes (Baji et al, 2010;Ge et al, 2004;Go et al, www.intechopen.com 2004; Haggenmueller et al, 2003;Jang et al, 2009;Ji et al, 2009;Kang et al, 2009;Razal et al, 2007;Vigolo et al, 2000Vigolo et al, , 2002, similar improvements were also observed. For instance, aligned nanotube/polyacrylonitrile fibers after hot-stretching treatment showed a significant enhancement of tensile strength by 320.7% (Ji et al, 2009), while aligned nanotube/epoxy arrays induced by electric field could improve electrical conductivities by four orders of magnitude in the direction of alignment .…”

“…For instance, high-quality nanotube/polydiacetylene composite fibers were produced by the physical attachment of diacetylenic monomers followed by topochemical polymerization of diacetylenic moieties under UV light . Another widely explored method to aligned nanotube/polymer fibers is electrospinning, an electrostatically induced self-assembly process where nanoscale fibers were typically produced (Baji et al, 2010;Ge et al, 2004;Go et al, 2004;Kang et al, 2009). The surface tension, jet elongation, and slow relaxation of nanotubes contribute to orientation of nanotubes.…”

“…One-dimensional nanostructures have received considerable attention due to their tunable physical and electroactive properties, such as mechanical strength, stiffness, ferromagnetism, ferroelectricity, etc [1][2][3][4][5][6][7][8][9]. In particular, nanostructured magneto-electric (ME) multiferroic materials with the coexistence of electric and magnetic order parameters are of great scientific and technological interest [1,2,8,[10][11][12][13][14].…”

We report the fabrication of novel multiferroic nanostructured bismuth ferrite (BiFeO 3 ) fibers using the sol-gel based electrospinning technique. Phase pure BiFeO 3 fibers were prepared by thermally annealing the electrospun BiFeO 3 /polyvinylpyrrolidone composite fibers in air for 1 h at 600• C. The x-ray diffraction pattern of the fibers (BiFeO 3 ) obtained showed that their crystalline structures were rhombohedral perovskite structures. Both scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed that the BiFeO 3 fibers were composed of fine grained microstructures. The grains were self-assembled and self-organized to yield dense and continuous fibrous structures. The magnetic hysteresis loops of these nanostructured fibers displayed the expected ferromagnetic behavior, whereby a coercivity of ∼250 Oe and a saturation magnetization of ∼1.34 emu g −1 were obtained. The ferroelectricity and ferroelectric domain structures of the fibers were confirmed using piezoresponse force microscopy (PFM). The piezoelectric hysteresis loops and polar domain switching behavior of the fibers were examined. Such multiferroic fibers are significant for electroactive applications and nano-scale devices.

The present work demonstrates a novel technique for dispersing nanofillers in a thermoplastic polymer, where polymerization and dispersion of the nanofillers occur simultaneously via dynamic emulsion polycondensation at ambient temperature. The composite is manufactured in the form of a uniform powder, which can then be molded into desired shape by melting or sintering. The technique is demonstrated for Ag nanowire / Nylon 66 composites. In this demonstration, Ag nanowires are synthesized by the polyol process. Polyvinylprrolidone (PVP) is used to functionalize the Ag nanowires. Nanocomposites with varying Ag content are prepared and investigated. The nanowires are found to be monodispersed and hydrogen-bonded to the Nylon 66 matrix through PVP. Glass transition temperature of the composites decreases from 61 to 48 °C with Ag weight fraction increasing from 0 to 6.47%. The depression of the glass transition temperature is owed to the plasticizer effect as well as heterogeneous nucleation effect of the nanowires for polymerization leading to shorter chain length.
