“…Furthermore, an incorporated filler with larger size and higher content will result in a greater reduction in permeability and mechanical performance, which restricts the materials’ application. This is mainly ascribed to the agglomeration of additives and heterogeneity, microstructure embrittlement and the discontinuity of electrospun nanofibers [ 55 ].…”

Fiber electronics, such as those produced by the electrospinning technique, have an extensive range of applications including electrode surfaces for batteries and sensors, energy storage, electromagnetic interference shielding, antistatic coatings, catalysts, drug delivery, tissue engineering, and smart textiles. New composite materials and blends from conductive–semiconductive polymers (C-SPs) offer high surface area-to-volume ratios with electrical tunability, making them suitable for use in fields including electronics, biofiltration, tissue engineering, biosensors, and “green polymers”. These materials and structures show great potential for embedded-electronics tissue engineering, active drug delivery, and smart biosensing due to their electronic transport behavior and mechanical flexibility with effective biocompatibility. Doping, processing methods, and morphologies can significantly impact the properties and performance of C-SPs and their composites. This review provides an overview of the current literature on the processing of C-SPs as nanomaterials and nanofibrous structures, mainly emphasizing the electroactive properties that make these structures suitable for various applications.

“…The porous structure allows thermal-moisture transfer and cellular respiration in the wound area . More importantly, the large specific surface area is particularly suitable as the tribo-layer of TENG because a greater contact area is beneficial for higher mechanical-to-electrical conversion efficiency . Therefore, the electrospun fibrous membrane has the ideal characteristics for wound dressing and the TENG.…”

Chronic wound healing is often impaired by bacterial infection and weak trans-epithelial potential. Patches with electrical stimulation and bactericidal activity may solve this problem. However, inconvenient power and resistant antibiotics limit their application. Here, we proposed a self-powered and intrinsic bactericidal patch based on a triboelectric nanogenerator (TENG). Electrospun polymer tribo-layers and a chemical vapordeposited polypyrrole electrode are assembled as the TENG, offering the patch excellent flexibility, breathability, and wettability. Electrical stimulations by harvesting mechanical motions and positive charges on the polypyrrole surface kill over 96% of bacteria due to their synergistic effects on cell membrane disruption. Moreover, the TENG patch promotes infected diabetic rat skin wounds to heal within 2 weeks. Cell culture and animal tests suggest that electrical stimulation enhances gene expression of growth factors for accelerated wound healing. This work provides new insights into the design of wearable and multifunctional electrotherapy devices for chronic wound treatment.

“…Electrospinning is a simple and cost-effective way to synthesize nanofiber films, which are used as the frictional layers of the TENG recently. − However, only the polymers with large molecular weights can form nanofibers by electrospinning, which greatly limits the choice of materials. Poly(dimethylsiloxane) (PDMS) is an excellent tribonegative layer material due to its great triboelectric property as well as flexibility .…”

Nanofiber-based triboelectric nanogenerators (TENGs) have garnered increasing attention as the multifunctional power source in wearable electronics. However, most traditional wearable device-based TENGs are unable to simultaneously achieve excellent outputs and multifunctional properties. Here, we design a waterproof, breathable, UV-protective TENG based on a poly(vinylidene fluoride) (PVDF)/poly(dimethylsiloxane) (PDMS)/TiO2 nanofiber film for effective harvesting mechanical energy by a simple and low-cost combined electrospinning/electrospray method. The introduction of PVDF can overcome the synthesis puzzle of PDMS nanofibers during the electrospinning process. With numerous three-dimensional micro-to-nano hierarchical pores of a nanofiber network, the constructed TENG can furnish large specific surface area and good breathability. The addition of TiO2 nanoparticles (NPs) increases the dielectric constant and surface roughness of the PVDF/PDMS/TiO2 nanofiber film as well as the corresponding output performance of the nanofiber-based TENG. The as-presented TENG has a maximum peak power density of 0.72 W/m2 and excellent breathability (18.6 mm/s). Due to the UV radiation absorbed by the TiO2 NPs, the UVA transmittance (T UVA) of the TENG with 4% TiO2 NPs is decreased to only 8.2%. The constructed TENG can be integrated to monitor human physiological signals in a self-powered manner. The nanofiber-based TENG provides a version to render these suitable for the daily-used wearable or portable electronics shortly.
