Abstract:The silver nanowires (AgNWs) and silver nanoparticles (AgNPs) were synthesized. With near-field electrospinning (NFES) process, fibers and thin films with AgNPs and AgNWs were fabricated. In the NFES process, 10 k voltage was applied and the AgNPs and AgNWs fibers can be directly orderly collected without breaking and bending. Then, the characteristics of the fibers were analyzed by four-point probe and EDS. The conductive film was analyzed. When the thickness of films with AgNWs and AgNPs was 1.6 m, the sheet… Show more
“…Pan et al used the mixed solution of AgNWs and AgNPs to prepare a transparent conductive film through the near-field electrospinning process. The film reached 70% transparency and 0.032 Ω/sq square resistance, which was similar to that of ITO [ 201 ]. Fig.…”

Silver nanowires (AgNWs), as one-dimensional nanometallic materials, have attracted wide attention due to the excellent electrical conductivity, transparency and flexibility, especially in flexible and stretchable electronics. However, the microscopic discontinuities require AgNWs be attached to some carrier for practical applications. Relative to the preparation method, how to integrate AgNWs into the flexible matrix is particularly important. In recent years, plenty of papers have been published on the preparation of conductors based on AgNWs, including printing techniques, coating techniques, vacuum filtration techniques, template-assisted assembly techniques, electrospinning techniques and gelating techniques. The aim of this review is to discuss different assembly method of AgNW-based conducting film and their advantages.

Electrospinning
is a straightforward and versatile method to fabricate ultrafine fibers
with unique physical and chemical properties. However, the chaotic
nature of traditional electrospinning limits its applications in devices
which usually need arranged or patterned micro/nanoscale fibrous structures.
In order to improve the controllable deposition of electrospun fibers,
near-field electrospinning (NFES) has been proposed and developed
in recent years. With characteristics of position-controlled deposition,
NFES significantly expands the range of fiber-fabrication uses including
electronic components, energy harvesting, flexible sensors, and tissue
engineering. In this paper, the basic principle and research advances
of NFES have been briefly reviewed. In particular, we summarize the
process parameters, polymer materials, as-spun fibrous structures,
modified apparatus, and potential applications of NFES. Finally, future
prospects on the development tendency and challenges of NFES are discussed.
“…The printed ribbons containing silver nanowires and polyethylene oxide composite structures were created by optimizing polymer and process parameters [23]. Moreover, polymers, including nanoparticles, were utilized to produce aligned, conductive, and transparent electrodes with a minimum diameter of 500 nm at high applied voltage [24]. The results of above-mentioned studies imply that electrospinning of the polymers with a conductive nature can cause flashovers, limiting the control of the precise nanopatterning due to the discharge of the high applied voltage between the needle and the collector [25].…”
