“…In another study, Mg(NO 3 ) 2 (10 wt % Mg 2+ relative to the polymer) was introduced into an aqueous mixture of poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(styrenesulfonate) (PSS). 91 Upon electrospinning, conductive nanofibers with diameters in the range of 70–100 nm were obtained (Figure 5B). The formation of nanofibers can be attributed to the introduced Mg 2+ ions, which served as a physical cross-linker for the polymer chains (Figure 5C).…”

Electrospinning is a versatile and viable technique for generating ultrathin fibers. Remarkable progress has been made with regard to the development of electrospinning methods and engineering of electrospun nanofibers to suit or enable various applications. We aim to provide a comprehensive overview of electrospinning, including the principle, methods, materials, and applications. We begin with a brief introduction to the early history of electrospinning, followed by discussion of its principle and typical apparatus. We then discuss its renaissance over the past two decades as a powerful technology for the production of nanofibers with diversified compositions, structures, and properties. Afterward, we discuss the applications of electrospun nanofibers, including their use as “smart” mats, filtration membranes, catalytic supports, energy harvesting/conversion/storage components, and photonic and electronic devices, as well as biomedical scaffolds. We highlight the most relevant and recent advances related to the applications of electrospun nanofibers by focusing on the most representative examples. We also offer perspectives on the challenges, opportunities, and new directions for future development. At the end, we discuss approaches to the scale-up production of electrospun nanofibers and briefly discuss various types of commercial products based on electrospun nanofibers that have found widespread use in our everyday life.

Textile electronics addresses fibers or fiber assemblies with electronic functions to generate, transmit, modulate, and detect electrons. Interactive textile electronic devices may provide suitable platforms for virtual reality (VR)/augmented reality (AR) applications because of their excellent performance and unique immersive features such as lightweight, handiness, flexibility, comfort, and low strain even under high deformations. This paper presents a systematic review of the literature on the state‐of‐the‐art of interactive devices, fabrication technologies, system integration, promising applications, and challenges involved in textile‐based VR/AR systems.

“…The use of polythiophene and its derivative, particularly, poly(3,4-ethylenedioxythiophene) (PEDOT) in bioengineering applications has been widely reported in the literature. − Pristine polythiophene was electrospun aided by either cross-linking reactions (magnesium ions as physical cross-linkers) or by utilizing “click” chemistry to add solubilizing side groups onto the CP. − However, a challenge to the prevalent use of PTh and its derivatives is that they are generally difficult to process and of poor mechanical properties . We have recently reported synthesis and properties of a range of novel, functionalized thiophene phenylene (ThP) monomers and their polymers (PThP) and discussed advantages of incorporation of functional side groups through the central benzene ring of the monomer on the properties of the obtained polymers, including solubility. , In this study, we utilize these PThP conducting polymers to demonstrate their processability by electrospinning into blend fiber mats with PLGA and PEO.…”

This research focuses on the design of biocompatible materials/scaffold suitable for use for tissue engineering. Porous fiber mats were produced through electrospinning of polythiophene phenylene (PThP) conducting polymers blended with poly(lactide- co-glycolic acid) (PLGA). A peptide containing an arginylglycylaspartic acid (RGD) fragment was synthesized using solid phase peptide synthesis and subsequently grafted onto a PThP polymer using azide-alkyne "click" chemistry. The obtained RGD functionalized PThP was also electrospun into a fiber mat. The electrospun mats' morphology, roughness and stiffness were studied by means of scanning electron microscopy (SEM) and atomic force microscopy (AFM) and their electroactivity by cyclic voltammetry. The fibers show excellent cytocompatibility in culture assays with human dermal fibroblasts-adult (HDFa) and human epidermal melanocytes-adult (HEMa) cells. The electrospun fibers' roughness and stiffness changed after exposing the fiber mats to the cell culture medium (measured in dry state), but these changes did not affect the cell proliferation. The cytocompatibility of our porous scaffolds was established for their applicability as cell culture scaffolds by means of investigating mitochondrial activity of HDFa and HEMa cells on the scaffolds. The results revealed that the RGD moieties containing PThP scaffolds hold a promise in biomedical applications, including skin tissue engineering.
