Special Issue Information

Dear Colleagues,

Electrospinning evolved as a practical, applicable, versatile, high-potential and simple technology to produce nano- to micro-scale fibers offering significant advantages due to their extremely high surface-to-volume ratio, high porosity and easy functional design. Recent years have witnessed tremendous progress in this field, driven mostly by innovative electrospinning systems and the design of functional polymer or ceramic micro/nanofibers.

The most recently developed electrospinning methods, such as multi-jet, needleless, bubble, centrifuge and electro-centrifuge systems, ensure a high production rate of micro- and nanofibers. Moreover, the design of novel nanocomposites and the morphological control of fibrous structures have attracted great interest for the development of applications of electrospun micro/nanofibers.

At present, electrostatically spun fibers, including polymer or ceramic fibers, are widely used in many fields, such as biomedicine (e.g., tissue engineering scaffolds, skin, poly (lactic-co-glycolic acid) (PLGA) sutures, bone, cartilage, neural tissues, muscles, drug delivery and release control, blood vessels, wound healing and enzyme carriers), environmental protection (e.g., filtration and metal ion adsorption) and energy harvesting and storage (e.g., solar cells, fuel cells, lithium ion batteries, mechanical energy harvesters, sensors, catalysts and flexible wearables).

Given their importance, this Special Issue of Materials invites contributions addressing all aspects of electrospun micro/nanofibers through experiments or theoretical simulations; these aspects may include innovative electrospinning technology, the optimization of micro/nanofiber mechanical properties, and potential applications of electrospun polymer or ceramic fibers. We warmly welcome original research works and review articles on the electrospinning of micro/nanofibers from experts and scholars worldwide.

Microwave absorbers with infrared camouflage are highly desirable in military fields. Self-supporting 3D architectures with tailorable shapes, composed of FeCoNi alloy/carbon nanotubes (CNTs) @ carbon nanofibers (CNFs), were fabricated in this study. On the one hand, multiple loss mechanisms were introduced into the high-elastic sponges. Controllable space conductive networks caused by the in situ growth of CNTs on the CNFs contributed to the effective dielectric and resistance loss. Moreover, the uniformly distributed magnetic alloy nanoparticles (NPs) with dense magnetic coupling resulted in magnetic loss. On the other hand, heterogeneous interfaces were constructed by multicomponent engineering, causing interfacial polarization and polarization loss. Furthermore, the internal structures of sponges were optimized by regulating the alloy NPs sizes and the growth state of CNTs, then tuning the impedance matching and microwave absorption. Therefore, the high-elastic sponges with ultra-low density (7.6 mg·cm−3) were found to have excellent radar and infrared-compatible stealth properties, displaying a minimum refection loss (RLmin) of −50.5 dB and a maximum effective absorption bandwidth (EABmax) of 5.36 GHz. Moreover, the radar stealth effect of the sponges was evaluated by radar cross-section (RCS) simulation, revealing that the multifunctional sponges have a promising prospect in military applications.
