Compared with traditional metal materials, carbon-based materials have the advantages of low density, high conductivity, good chemical stability, etc., and can be used as reliable alternative materials in various fields. Among them, the carbon fiber conductive network constructed by electrospinning technology has the advantages of high porosity, high specific surface area and rich heterogeneous interface. In order to further improve the conductivity and mechanical properties of pure carbon fiber films, tantalum carbide (TaC) nanoparticles were selected as conductive fillers. The crystallization degree, electrical and mechanical properties of electrospun TaC/C nanofibers at different temperatures were investigated. As the carbonization temperature increases, the crystallization degree and electrical conductivity of the sample also increases, while the growth trend of electrical conductivity is markedly slowed. The best mechanical properties of 12.39 MPa was achieved when the carbonization temperature was 1200 °C. Finally, through comprehensive analysis and comparison, it can be concluded that a carbonization temperature of 1200 °C is the optimum.

“…However, the preparation methods and techniques of the spiropyran-based materials reported currently are complex and costly, making them difficult to produce on a large scale and limiting their practical applications. A simple and feasible large-area preparation method is needed if spiropyran-based functional materials used to regulate microenvironmental humidity can be realized . Electrospinning as a multifunctional technology opens a new window for smart fibers, which has attracted a lot of attention in the recent decades due to the simple method of producing micro- or even subnanometer fibers with excellent mechanical properties and especially flexibility .…”

Based on the goal to improve the humidity index of the microenvironment and enhancing human comfort, this study used electrospinning to prepare several photoresponsive films with reversible regulation of wettability and microenvironmental humidity from copolymers of acrylated spiropyran (SPA), N-isopropylacrylamide (NIPAm), and methyl methacrylate (MMA). According to the photoisomerization mechanism of spiropyran, the simple ultraviolet (UV)–visible light (vis) reversible light radiation change makes the spiropyran unit switch between the polar ring-opened form and the nonpolar ring-closed form. Utilizing this transition can easily regulate the wettability of the film surface and microenvironmental humidity. The experimental results show that poly(SPA1-co-NIPAm2-co-MMA8) nanowire film has the best ability to regulate wettability and humidity; the wettability can vary within a range of 13° and the microenvironmental humidity up to 7.2%.

“…Although this is a relatively straightforward and inexpensive method, the membrane it produces might not be uniform. Electrospinning: in order to create a membrane, this method uses an electric field to pull polymer fibers out of a solution and deposit them there [ 37 , 38 ]. Although it can take some time, electrospinning creates a membrane that is highly porous and uniform.…”

Hydrogen energy is converted to electricity through fuel cells, aided by nanostructured materials. Fuel cell technology is a promising method for utilizing energy sources, ensuring sustainability, and protecting the environment. However, it still faces drawbacks such as high cost, operability, and durability issues. Nanomaterials can address these drawbacks by enhancing catalysts, electrodes, and fuel cell membranes, which play a crucial role in separating hydrogen into protons and electrons. Proton exchange membrane fuel cells (PEMFCs) have gained significant attention in scientific research. The primary objectives are to reduce greenhouse gas emissions, particularly in the automotive industry, and develop cost-effective methods and materials to enhance PEMFC efficiency. We provide a typical yet inclusive review of various types of proton-conducting membranes. In this review article, special focus is given to the distinctive nature of nanomaterial-filled proton-conducting membranes and their essential characteristics, including their structural, dielectric, proton transport, and thermal properties. We provide an overview of the various reported nanomaterials, such as metal oxide, carbon, and polymeric nanomaterials. Additionally, the synthesis methods in situ polymerization, solution casting, electrospinning, and layer-by-layer assembly for proton-conducting membrane preparation were analyzed. In conclusion, the way to implement the desired energy conversion application, such as a fuel cell, using a nanostructured proton-conducting membrane has been demonstrated.
