“…(5) Attachment of polyphenolic compounds to the surface of nanofibers [ 162 ]. To improve production efficiency and reduce production time and cost, several techniques for preparing nanofibers have been developed, such as electrospinning, solution blow spinning, centrifugal spinning, and carbon dioxide laser supersonic drawing [ [163] , [164] , [165] , [166] , [167] ]. Wang et al used an electrospinning technique to load curcumin in zein fibers successfully with a high EE of nearly 100%, and the nanofibers manifested a remained antioxidant capability and an enhanced antibacterial effect against S. aureus and E. coli [ 168 ] .…”

“…The top‐down approaches rely on etching away the bulk material by physical, [ 43,44 ] biological, [ 45,46 ] or chemical [ 47,48 ] treatments to achieve the required structural fibers. In contrast, the bottom‐up approaches involve the fibrous structures being assembled atom by atom or molecule by molecule via covalent or supramolecular interactions, as drawing, [ 49 ] template synthesis, [ 50 ] self‐assembly, [ 51 ] phase separation, [ 52 ] and spinning process. [ 9,53 ] Over the last years, spinning techniques such as electrospinning [ 4,10,54 ] and solution blow spinning [ 55–57 ] have attracted great interest due to their simplicity, versatility in terms of composition and architecture of fibers, and scale‐up potential.…”

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.

“…There is a variety of techniques to obtain nanofibers: supersonic laser drawing with CO2 [13], spinning by solution blowing [14], centrifugal jet spinning [15], direct electrodynamic drawing [16], and others [17]. However, the most established technique for producing nanofibers in a continuous form is electrospinning [9,18].…”

La contaminación de los cuerpos de agua es uno de los problemas medioambientales más comunes en la actualidad. Los contaminantes orgánicos son uno de los compuestos perjudiciales más importantes, entre los que destacan los colorantes de larga vida, los productos farmacéuticos y los pesticidas. Esta investigación tiene como objetivo la obtención de nanocompositos basados en nanofibras (NFs) electrohiladas de policaprolactona-quitosano (PCL-CS) con nanopartículas de TiO2 (TiO2NPs) para la adsorción y degradación fotocatalítica de contaminantes orgánicos, utilizando como modelo la rodamina B. Los materiales híbridos fabricados se caracterizaron por FT-IR, TGA, DSC, SEM, TEM, propiedades de tracción y ángulo de contacto de gotas de agua. La fotoactividad de las NFs se investigó utilizando un sistema tipo “batch” seguida por espectroscopia UV-Vis y microscopia de fluorescencia. Para este propósito, se incorporaron ex-situ las TiO2NPs a la matriz polimérica mostrando buenas propiedades mecánicas y una mayor hidrofilicidad del material. Los resultados mostraron que la presencia de CS en las NFs aumentaba la absorción y degradación de RhB por las TiO2NPs. El CS atrae las moléculas contaminantes a los sitios activos como las TiO2NPs, favoreciendo la adsorción y degradación. En otras palabras, se evidenció un efecto anzuelo-y-destrucción (bait-hook-and-estroy effect). También se demostró que la sensibilización del TiO2 mediante colorantes orgánicos (por ejemplo, un derivado del perileno) mejora considerablemente la actividad fotocatalítica bajo radiación visible, permitiendo el uso de bajas cantidades de TiO2. (≈0,05 g/1 g de fibra). Por lo tanto, se espera que el presente estudio contribuya con una solución alternativa ecológica y respetuosa con el medio ambiente.
