Polymer Nanofibers and Nanotubes: Charge Transport and Device Applications

Abstract

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.

Formation of β-Phase Crystalline Structure of PVDF Nanofiber by Electrospray Deposition: Additive Effect of Ionic Fluorinated Surfactant

“…Recently, nanofibers and nanofiber mats with high specific surface area have attracted much attention for the applications such as filter media, 1 protective clothing, 2 aerospace materials, 3 electronic devices, 4 tissue engineering, 5,6 sensors, 7 and biomedical uses. 8,9 Particularly, the slip flow effect on the surface of nanofiber is potentially useful for high-efficiency air filters.…”

Density of states anomalies in multichannel quantum wires

“…Experimental realizations of TLL states encompass various systems showing highly anisotropic conductivity: metallic, 17,18 semiconducting, [19][20][21][22][23][24][25] and organic nanowires, [26][27][28][29][30] and carbon nanotubes 9,10,[31][32][33][34] are a few examples. These actual quasi-1D conductors possess a finite cross-section, thus exhibiting a finite number of transmission channels in the transverse direction (except for a limited case in which E F is small enough for only the lowest subband to be involved).…”

Electrospinning for nano- to mesoscale photonic structures

“…For example, anisotropy of organic nanowires (ONWs) facilitates the propagation of light and electricity in specific spatial directions [117]. The π-π conjugated morphology [118,119] of ONWs [120] coupled with established charge transport according to the molecular packing orientation [121,122] provides favorable emergent properties for electronic devices and highly efficient energy harvesting devices with extremely high aspect ratio and large surface area-to-volume ratio [123][124][125]. Solid, 1D organic nanorods (ONRs) with moderate aspect ratio and high surface area have provided good performance for supercapacitor electrodes [86] and greatly improved photostability for biological imaging applications [126].…”
