“…Natural biopolymers, including silk fibroin, chitosan, and collagen, are also widely used in electrospinning research. When nanoscale components such as nanoparticles [140][141][142], nanotubes [143][144][145], nanowires [146,147], or nanorods [148][149][150] are incorporated into the polymer solutions, electrospun nanocomposites that combine the properties of both components can be generated.

Inherently conductive polymers (CPs) can generally be switched between two or more stable oxidation states, giving rise to changes in properties including conductivity, color, and volume. The ability to prepare CP nanofibers could lead to applications including water purification, sensors, separations, nerve regeneration, wound healing, wearable electronic devices, and flexible energy storage. Electrospinning is a relatively inexpensive, simple process that is used to produce polymer nanofibers from solution. The nanofibers have many desirable qualities including high surface area per unit mass, high porosity, and low weight. Unfortunately, the low molecular weight and rigid rod nature of most CPs cannot yield enough chain entanglement for electrospinning, instead yielding polymer nanoparticles via an electrospraying process. Common workarounds include co-extruding with an insulating carrier polymer, coaxial electrospinning, and coating insulating electrospun polymer nanofibers with CPs. This review explores the benefits and drawbacks of these methods, as well as the use of these materials in sensing, biomedical, electronic, separation, purification, and energy conversion and storage applications.

“…MNFNs constructed on electrospun polymer networks are another category of attractive structured metallic TEs due to their excellent performance . First, fabricated metallic nanofibers can easily achieve an aspect ratio up to 10 5 because of the extremely long profile of electrospun polymer nanofibers; this aspect ratio is much larger than that of ultralong AgNWs (≈1000) .…”

Metallic nanofiber networks (MNFNs) are very promising for next-generation flexible transparent electrodes (TEs) since they can retain outstanding optical and electrical properties during bending due to their ultralong and submicron profile. However, it is still challenging to achieve cost-effective and highthroughput fabrication of MNFNs with reliable and consistent performance. Here, a cost-effective method is reported to fabricate high-performance MNFN-TEs via templated electrodeposition and imprint transfer. The fabricated electrodeposition template has a trilayer structure of glass/indium tin oxide/SiO 2 with nanotrenches in the insulating SiO 2 that can be utilized for repeated electrodeposition of the MNFNs, which are then transferred to flexible substrates. The fabricated TEs exhibit excellent optical transmittance (>84%) and electrical conductivity (<0.9 Ω sq −1 ) and show desirable mechanical flexibility with a sheet resistance <2 Ω sq −1 under a bending radius of 3 mm. Meanwhile, the MNFN-TEs reproduced from the reusable template show consistent and reliable performance. Additionally, this template-based method can realize the direct patterning of MNFN-TEs with arbitrary conductive patterns by selective masking of the template. As a demonstration, a flexible dynamic electroluminescent display is fabricated using TEs made by this method, and the light-emitting pattern is observable from both sides.
