“…Besides the two strategies mentioned above, more improvements such as conductive temp late method [66,67], centri fugal electrospinning [68−70], and n ear-field electrospinning methods [71−74] have also been developed. Conductive template method can be used to prepare NWs with complex ordered architectures and patterns [67].…”

Electrospinning is a cheap and stable technique that allows the fabrication of continuous and uniform fibers, either organic or inorganic, with diameters ranging from tens of nanometers to several micrometers for mass production [5−7]. Moreover, highly ordered aligned nanowire array (NWA) can also be easily achieved on various substrates based on modified electrospinning, which is greatly beneficial to the following applications of NWs in various fields shown in Fig. 1. In this review, we provide a concise retrospection on the assembling methods and primarily highlight the electrospinning method and corresponding applications of NWA including electrodes, field effect transistors (FET), piezoelectric sensor, gas sensor, and photodetectors. We also give comments and prospection in the ABSTRACT Alignment of NWs (NWs) is the core issue for integrating NWs into nanodevices in future. This review made a concise retrospect on reported assembling methods and mainly emphasized on the electrospinning method and its developments, as well as the following applications of the aligned nanowire array (NWA) in electronics and optoelectronics. First, we classified reported assembling methods into three categories: "grow then place", "place then grow" and "grow and place" (electrospinning method). Then, we focused on the electrospinning method and its modified method including field assisted method, rotating collector assisted method and near-field assisted methods, as well as their merits and defects, respectively. Next, we illustrated the applications of the NWs arrays fabricated by electrospinning in field effect transistors (FET), gas sensors, piezoelectric sensors and photodetectors. Finally, we made a short conclusion and prospection on electrospinning method. As an easy and cheap nanowire fabrication and alignment method, electrospinning has a bright future in one-dimensional materials based electronics and optoelectronics.

“…Another technique called field-enhanced electrospinning has been reported to assemble and pattern as-spun fibers. 166 Polymer fibers were spun on an elastomeric substrate with gold-coated pyramidal protrusions with majority of fibers being deposited at the tips, and nanofiber pattern selectivity is highly dependent on the separation/size ratio of the pyramidal protrusions with a ratio of o1. …”

Recent advances in large-scale assembly of semiconducting inorganic nanowires and nanofibers for electronics, sensors and photovoltaics

Semiconducting inorganic nanowires (NWs), nanotubes and nanofibers have been extensively explored in recent years as potential building blocks for nanoscale electronics, optoelectronics, chemical/biological/ optical sensing, and energy harvesting, storage and conversion, etc. Besides the top-down approaches such as conventional lithography technologies, nanowires are commonly grown by the bottom-up approaches such as solution growth, template-guided synthesis, and vapor-liquid-solid process at a relatively low cost. Superior performance has been demonstrated using nanowires devices. However, most of the nanowire devices are limited to the demonstration of single devices, an initial step toward nanoelectronic circuits, not adequate for production on a large scale at low cost. Controlled and uniform assembly of nanowires with high scalability is still one of the major bottleneck challenges towards the materials and device integration for electronics. In this review, we aim to present recent progress toward nanowire device assembly technologies, including flow-assisted alignment, Langmuir-Blodgett assembly, bubble-blown technique, electric/magnetic-field-directed assembly, contact/roll printing, planar growth, bridging method, and electrospinning, etc. And their applications in high-performance, flexible electronics, sensors, photovoltaics, bioelectronic interfaces and nano-resonators are also presented.

“…Figure 3 shows a variety of collectors and their effect on the nanofiber mat pattern. Ding et al recently demonstrated the selective deposition of nanofibers on an elastomeric substrate containing gold-coated pyramidal spikes [69]. Star and radial fiber patterns have also been prepared using enamel patterned steel-sheet collectors [70].…”

Abstract:Traditional electrospun nanofibers have a myriad of applications ranging from scaffolds for tissue engineering to components of biosensors and energy harvesting devices. The generally smooth one-dimensional structure of the fibers has stood as a limitation to several interesting novel applications. Control of fiber diameter, porosity and collector geometry will be briefly discussed, as will more traditional methods for controlling fiber morphology and fiber mat architecture. The remainder of the review will focus on new techniques to prepare hierarchically structured fibers. Fibers with hierarchical primary structures-including helical, buckled, and beads-on-a-string fibers, as well as fibers with secondary structures, such as nanopores, nanopillars, nanorods, and internally structured fibers and their applications-will be discussed. These new materials with helical/buckled morphology are expected to possess unique optical and mechanical properties with possible applications for negative refractive index materials, highly stretchable/high-tensile-strength materials, and components in microelectromechanical devices. Core-shell type fibers enable a much wider variety of materials to be electrospun and are expected to be widely applied in the sensing, drug delivery/controlled release fields, and in the encapsulation of live cells for biological applications. Materials with a hierarchical secondary structure are expected to provide new superhydrophobic and self-cleaning materials.
