“…[75] It has been shown that electrospinning is a promising method to obtain PANi-based nanocables. [16,23,76] In addition, FET behavior has been reported recently for PANi-CSA/PEO nanofibers made by electrospinning. [69] Saturation channel currents were observed at surprisingly be coupled with a well-controlled high-k gate insulator and a metal gate with an appropriate workfunction.…”

Polymer Nanofibers and Nanotubes: Charge Transport and Device Applications

2005

View full text Add to dashboard Cite

A critical analysis of recent advances in synthesis and electrical characterization of nanofibers and nanotubes made of different conjugated polymers is presented. The applicability of various theoretical models is considered in order to explain results on transport in conducting polymer nanofibers and nanotubes. The relationship between these results and the one-dimensional (1D) nature of the conjugated polymers is discussed in light of theories for tunneling in 1D conductors (e.g. Luttinger liquid, Wigner crystal). The prospects for nanoelectronic applications of polymer fibers and tubes as wires, nanoscale field-effect transistors (nanoFETs), and in other applications are analyzed.

“…The presence of FeCl 3 drives the polymerization of pyrrole in the PVP matrix. FeCl 3 is an efficient oxidant for pyrrole polymerization, doping chlorine ions in the PPy to make it electrically conducting [28][29][30][31] The two flows were controlled independently using syringe pumps. The typical feeding rate for the two solutions was 0.01 mL/ min.…”

Microfluidic electrospinning of biphasic nanofibers with Janus morphology

2009

In this paper a method of electrospinning conducting and nonconducting biphasic Janus nanofibers using microfluidic polydimethylsiloxane ͑PDMS͒-based manifolds is described. Key benefits of using microfluidic devices for nanofiber synthesis include rapid prototyping, ease of fabrication, and the ability to spin multiple Janus fibers in parallel through arrays of individual microchannels. Biphasic Janus nanofibers of polyvinylpyrrolidone ͑PVP͒ + polypyrrole ͑PPy͒/PVP nanofibers with an average diameter of 250 nm were successfully fabricated using elastomeric microfluidic devices. Fiber characterization and confirmation of the Janus morphology was subsequently carried out using a combination of scanning electron microscopy, energy dispersion spectroscopy, and transmission electron microscopy.

“…It can be synthesized from either a condensation polymerization of lactic acid or ring opening polymerization of lactide, a cyclic dimmer of lactic acid [8]. Polylactide fibers were prepared here by an electro-spun technique using literature method [9]. The fibers used in this experiment were on average about 700 nm in diameter.…”

Synthesis of Novel Vanadium Oxide Nanotubes and Nanofibers

et al. 2002

We are exploring the synthesis and properties of structured vanadium oxides mainly nanotubes and nanorods. Nanotubes initially formed with surfactant templates have been readily exchanged with simple cations without change of the basal-plane structure. These compounds contain 8-like vanadium oxide layers with the vanadium in V0 6 octahedra. This structure is particularly suitable for redox reactions. In this paper we report on synthesis of vanadium oxide, (NH 4 ).V 2 0 5 _.nH 2 0 rods using organic polymer as template. This compound has been synthesized by sol-gel reaction and subsequent hydrothermal treatment. TGA, SEM, XRD and FTIR were used to characterize this compound. Thermal analysis of this compound shows that the fibrous morphology is maintained when it is heated in nitrogen and oxygen above 300 'C. However, in both cases the size of the fibers decreases. Performance of this compound as cathode material in secondary electrolyte has been investigated using LiPF 6 as electrolyte. A capacity of 140 mAh/g was obtained which remained fairly constant with up to at least 10 cycles. We also investigated electrochemical behavior of thermal products.
