Micro‐ and nanofibers produced by electrospinning and solution blow spinning (SBS) are highly suitable platforms for diverse applications due to their advantageous properties, including the high surface area to volume ratio, high porosity, and flexibility. To render them additional functionalities, distinct pre‐ or post‐modification processes have been proposed for modifying such micro‐ and nanofibers with 0D, 1D, 2D, and 3D nanostructures. The pre‐modification requires the addition of 0D–3D nanostructures (or their precursors) into the polymeric phase before the spinning process, which can demand laborious solubilization and requires changes in experimental spinning parameters, with impact on morphology, spinnability, and properties. Post‐modification methods, on the other hand, enable the fabrication of composite fibers without the need to optimize the spinning parameters, allowing a simple and efficient surface modification. Herein, recent advances on post‐modification methods of spun fibers, including wet chemistry, grafting, crosslinking, click chemistry, oxidations, hydrolysis and reduction strategies, dip‐coating, layer‐by‐layer, electro/air‐spray, atomic layer deposition, and plasma techniques aiming at the surface functionalization with 0D–3D nanostructures are surveyed. Recent results, trends, and challenges on the application of such surface‐modified fibers for environmental, industrial, and medical applications, including as adsorbent and filtering membranes, catalysts for pollutants degradation, and wearable sensors are examined.

“…In fact, some natural grown biopolymers and substances were also studied for electrospinning fibers to develop the so-called sustainable processing technology. Typical examples include the uses of starches [57], dextrins [58], and lignin [59]. The spun fibers could serve as the precursors of carbon fibers.…”

The objective of this article is to provide an overview on the current development of micro- and nanoporous fiber processing and manufacturing technologies. Various methods for making micro- and nanoporous fibers including co-electrospinning, melt spinning, dry jet-wet quenching spinning, vapor deposition, template assisted deposition, electrochemical oxidization, and hydrothermal oxidization are presented. Comparison is made in terms of advantages and disadvantages of different routes for porous fiber processing. Characterization of the pore size, porosity, and specific area is introduced as well. Applications of porous fibers in various fields are discussed. The emphasis is put on their uses for energy storage components and devices including rechargeable batteries and supercapacitors.
