“…Conductive fibres containing PEDOT may be formed by electrospinning, extruding a PEDOT:coion suspension under a high voltage electric field to form fibres which are collected on a substrate (Kitto et al 2019, Xue et al 2019. Optimised formulations including carrier polymers such as poly(vinyl alcohol) (PVA), Polycaprolactone (PCL) and poly(ethylene oxide) (PEO) are used to achieve electrospinnable PEDOT:co-ion mixtures (Bessaire et al 2017, Babaie et al 2020, Ritzau-Reid et al 2020, Lerond et al 2022, and conductivity enhancers including silver nanoparticles and graphene oxide may be added (Liu et al 2022, Ngoensawat et al 2022. Electrospinning can form conductive, porous, fibrous lattices for tissue engineering (Babaie et al 2020, Ritzau-Reid et al 2020, and additional PEDOT coatings may be electropolymerised onto conductive fibres after electrospinning (Zubair et al 2016).…”

Conductive polymers are of great interest in the field of neural electrodes because of their potential to improve the interfacial properties of electrodes. In particular, the conductive polymer poly (3,4)-ethylenedioxithiophene (PEDOT) has been widely studied for neural applications. This review compares methods for electrodeposition of PEDOT on metal neural electrodes, and analyses the effects of deposition methods on morphology and electrochemical performance. The findings of this review show that: coating thickness and charge storage capacity are positively correlated with PEDOT electrodeposition charge density. We also show that PEDOT coated electrode impedance at 1 kHz, the only consistently reported impedance quantity, is strongly dependent upon electrode radius across a wide range of studies, because PEDOT coatings reduces the reactance of the complex impedance, conferring a more resistive behavior to electrodes (at 1 kHz) dominated by the solution resistance and electrode geometry. This review also summarises how PEDOT co-ion choice affects coating structure and morphology and shows that co-ions notably influence the charge injection limit but have a limited influence on charge storage capacity and impedance. Finally we discuss the possible influence of characterisation methods to assess the robustness of comparisons between published results using different methods of characterisation.

“…The sensing materials used for detecting heavy metals have attracted widespread attention and research. Ngoensawat et al [ 93 ] fabricated a conductive nanofiber composite containing poly (3,4-ethylenedioxythiophene) (PEDOT) and silver nanoparticles (AgNPs) prepared by emulsion electrospinning, as shown in Figure 7 a. The heavy metal ion sensor assembled on the surface of the screen-printed carbon electrode using this conductive composite material presents a good electrochemical response and can simultaneously detect heavy metal ions, namely Zn (II), Cd (II), and Pb (II), in the mixture by square wave anodic stripping voltammetry.…”

Due to its designable nanostructure and simple and inexpensive preparation process, electrospun nanofibers have important applications in energy collection, wearable sports health detection, environmental pollutant detection, pollutant filtration and degradation, and other fields. In recent years, a series of polymer-based fiber materials have been prepared using this method, and detailed research and discussion have been conducted on the material structure and performance factors. This article summarizes the effects of preparation parameters, environmental factors, a combination of other methods, and surface modification of electrospinning on the properties of composite nanofibers. Meanwhile, the effects of different collection devices and electrospinning preparation parameters on material properties were compared. Subsequently, it summarized the material structure design and specific applications in wearable device power supply, energy collection, environmental pollutant sensing, air quality detection, air pollution particle filtration, and environmental pollutant degradation. We aim to review the latest developments in electrospinning applications to inspire new energy collection, detection, and pollutant treatment equipment, and achieve the commercial promotion of polymer fibers in the fields of energy and environment. Finally, we have identified some unresolved issues in the detection and treatment of environmental issues with electrospun polymer fibers and proposed some suggestions and new ideas for these issues.

Electrospun nanofibers have shown their advantages for applications in a wide variety of scientific fields thanks to their unique properties. Meanwhile, electrospinning is closely following the fast development of nano science and nanotechnology to move forward to smaller (pico-technology), more complicated nanostructures/nanodevices and more order (all kinds of nano arrays). Particularly, multiple-fluid electrospinning has the strong capability of creating nanostructures from a structural spinneret in a single-step and a straightforward “top-down” manner, holding great promise for creation on a large scale. This review is just to conclude the state-of-art studies on the related topics and also point out that the future directions of environmental detection require chemosensors, while the improvement of sensors requires new chemically synthesized functional substances, new nanostructured materials, application convenience, and functional integration or synergy. Based on the developments of electrospinning, more and more possibilities can be drawn out for detecting environmental pollutants with electrospun nanostructures as the strong support platform.
