In recent years, electrospun nanofibers made of various materials (e.g., polymers, composites, and semiconductors) have been extensively studied for the development of highly sensitive and selective gas sensors. These nanofibers possess unique three-dimensional (3D) interconnected porous structures that result in a large surface-area-to-volume ratio and high porosity. These properties have led to the widespread use of nanofibrous mats as active materials for mass-sensitive sensors, which use the gravimetric effect to measure the mass concentration of the adsorbed gases on their active surfaces. For this purpose, quartz crystal microbalance (QCM) has been considered as one of the most favorable mass-sensitive platforms because of its mature technology, low-cost production, fast sensing response, and highly flexible sensing area modification. This paper provides an overview of state-of-the-art QCM-based gas sensors that integrate electrospun nanofibers as their active materials. Several key parameters determining the sensor performance (e.g., sensitivity and limit of detection (LOD)) are summarized and discussed in relation to the current challenges. Finally, the outlook for future technological development is also provided.

“…Conductive nanofibers have potential applications like corrosion protection, electromagnetic interference shielding, photovoltaic device, electrostatic dissipation and fabrication of tiny electronic devices or machines such as Schottky junctions, sensors and actuators [2,143,144]. Conductive nanofibrous materials are suitable for use as a porous electrode in improving high-performance battery and polymer electrolyte membrane fuel cells because it had high porosity and inherent large total surface area (Fig 10).…”

“…Electrospinning is a process used for produce polymer fibers in the submicron range using polymer melts or solution of both natural and synthetic polymers [1][2][3]. The properties of these fibers are difficult to achieve by using other technology techniques (like greater surface area and smaller pores size than regular fibers) [3][4][5].…”

E LECTROSPUN nanofibers have found many applications as useful material with reasonable properties and morphology. The electrospinning technique is better than other conventional nanofiber fabrication techniques owing to the ease of formation and controlling fiber orientation. Electrospun nanofiber has unique properties such as a high surface area to volume ratio, easily in surface functionality, interfibrous pore sizes, and the ability to change the nanofiber composition to get specific functions and properties. The current review highlights the electrospinning principles, types of electrospinning, and the parameters that affect the nanofibers fabrication. Finally, we provided some nanofiber applications area such as biomedical, protective clothing, sensors, electrical, and filtration.

“…20,21 In these composite materials, carbon nanomaterials induce high electrical conductivity while a polymer matrix acts as the structural material while also providing bendability and conformability as required for flexible electronics applications. 4,22,23 Nanocomposites based on single-walled carbon nanotubes on polyethylene oxide nanofiber mats, 24 and poly(vinyl alcohol) nanofibers embedded with titanium nanoparticles 25 were demonstrated for biosensor and gas sensor applications, respectively. Among carbon nanomaterials, carbon nanotubes (CNTs) and 2-D graphene have been studied to a much greater extent than carbon nanofibers (CFs).…”
