“…At the same time, electrospinning technology is widely used in the preparation of ENMs due to their high porosity, ease of preparation, and high specific surface area [139]. Nanofiber membranes are also well used in industrial production for water treatment [11,140]. In this review, we report the latest research on the removal of heavy metals and dyes from water by nanocomposite fiber membranes.…”

With the rapid development of nanotechnology, electrospun nanofiber membranes (ENM) application and preparation methods have attracted attention. With many advantages such as high specific surface area, obvious interconnected structure, and high porosity, ENM has been widely used in many fields, especially in water treatment, with more advantages. ENM solves the shortcomings of traditional means, such as low efficiency, high energy consumption, and difficulty in recycling, and it is suitable for recycling and treatment of industrial wastewater. This review begins with a description of electrospinning technology, describing the structure, preparation methods, and factors of common ENMs. At the same time, the removal of heavy metal ions and dyes by ENMs is introduced. The mechanism of ENM adsorption on heavy metal ions and dyes is chelation or electrostatic attraction, which has excellent adsorption and filtration ability for heavy metal ions and dyes, and the adsorption capacity of ENMs for heavy metal ions and dyes can be improved by increasing the metal chelation sites. Therefore, this technology and mechanism can be exploited to develop new, better, and more effective separation methods for the removal of harmful pollutants to cope with the gradually increasing water scarcity and pollution. Finally, it is hoped that this review will provide some guidance and direction for research on wastewater treatment and industrial production.

“…Particulate matter (PM) with an aerodynamic diameter of less than 2.5 μm (PM 2.5 ) seriously affects the health of individuals by penetrating into the human lungs and bronchial tubes . Therefore, the development of high-performance air filter (i.e., high filtration efficiency and low pressure drop) has become a hot research topic because it can balance protection and comfort. − In recent years, nanofibrous membranes have become the first choice for high-performance air filtration because of their large specific surface area, high porosity, and fine fiber diameter. − Electrospinning is a simple and versatile method to produce nanofibrous membrane. − Until now, many materials have been used for electrospinning, such as polyamide (PA), polyacrylonitrile (PAN), polyimide (PI), polyvinylidene fluoride (PVDF). − However, the common problems with these petroleum-derived synthetic polymers are that they are nonrenewable and nonbiodegradable, causing an energy crisis and environmental pollution. Fortunately, electrospinning preparation strategies based on biobased materials and green solvents have been developed.…”

Biobased high-performance air filters via green electrospinning are the key to reducing the energy crisis and the environmental burden. However, the complicated postprocessing limits its application. In this research, a green solution system with delayed volatilization was constructed, and a zein/cinnamaldehyde (CMA) composite nanofibrous membrane with optimized structure was produced by one-step electrospinning. The addition of CMA significantly decreased the volatility of the solution, deferring the clogging time of the nozzle and thus smoothing the electrospinning process. The time from the start of electrospinning to nozzle blockage increased by over 300%, resulting in a significant improvement in fiber morphology. The air filtration efficiency for PM0.3, the pressure drop, and the quality factor were 99.25%, 58.2 Pa, and 0.084 Pa–1, respectively, compared to the membrane without CMA addition and N95 mask. Moreover, the CMA improved the hydrophobicity of the zein nanofiber, which helped improve the stability of air filtration and endowed the nanofibers with certain antibacterial properties. This work is the first to report that CMA improves continuity in electrospinning, which will promote the development of green electrospinning and the preparation of a high-performance biobased air filter.
