“…Electrospun nanofibers provide new platform for the design of novel sensors with high sensitivity, selectivity, capability, and portability [10,83]. This is a result of their unique features, which include their large surface-to-area ratio, malleable mechanical properties, and the ease of surface functionality modification.…”

“…This is a result of their unique features, which include their large surface-to-area ratio, malleable mechanical properties, and the ease of surface functionality modification. Different sensing agents can be embedded into electrospun nanofibers, thereby enhancing the sensitivity, response time, and detection level (lowest detection concentration) [10,83]. Alginate having carboxyl and hydroxyl groups can be functionalized with heavy metal-sensitive compounds, since it can bind to the multivalent ions and thus can be detected easily [10,84].…”

“…On the other hand, electrospun alginate nanofibers, as an excellent battery electrode, can be explored in energy storage materials [83,87,88]. Similarly, a large number of carboxyl groups along alginate chains offers the sites for accommodating the nanoparticles for battery electrode, thereby enhancing the overall performance of the battery, as demonstrated by Kavalenko et al [82].…”

Alginate has been a material of choice for a spectrum of applications, ranging from metal adsorption to wound dressing. Electrospinning has added a new dimension to polymeric materials, including alginate, which can be processed to their nanosize levels in order to afford unique nanostructured materials with fascinating properties. The resulting nanostructured materials often feature high porosity, stability, permeability, and a large surface-to-volume ratio. In the present review, recent trends on electrospun alginate nanofibers from over the past 10 years toward advanced applications are discussed. The application of electrospun alginate nanofibers in various fields such as bioremediation, scaffolds for skin tissue engineering, drug delivery, and sensors are also elucidated.

“…This type of device is known as a luminescent solar concentrator (LSC) and has been realized in the form of either planar or cylindrical waveguides [ 6 , 7 , 8 , 9 ]. Furthermore, PL waveguides are also utilized for optical communication, sensing, and illumination [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

“…However, employing differently colored fibers does not alleviate intrafiber self-absorption [ 32 ]; only part of the light that would otherwise be radiated away from the system is recaptured by adjacent waveguides. Adjusting the emission color of luminescent textiles by carefully selecting unicolor PL-POFs is crucial in such systems, and it is application specific, e.g., as decorative elements or colored emitters under white-light illumination [ 15 , 33 , 34 , 35 , 36 ]. The present study shows, to the best of our knowledge, for the first time, how the effect of fiber-to-fiber light transfer in multicolor PL textiles can be utilized and optimized towards color-tunability based on the two principles textile composition and dye concentration of the individual fibers constituting the fabrics.…”

Melt-Spun Photoluminescent Polymer Optical Fibers for Color-Tunable Textile Illumination

2021

The increasing interest in luminescent waveguides, applied as light concentrators, sensing elements, or decorative illuminating systems, is fostering efforts to further expand their functionality. Yarns and textiles based on a combination of distinct melt-spun polymer optical fibers (POFs), doped with individual luminescent dyes, can be beneficial for such applications since they enable easy tuning of the color of emitted light. Based on the energy transfer occurring between differently dyed filaments within a yarn or textile, the collective emission properties of such assemblies are adjustable over a wide range. The presented study demonstrates this effect using multicolor, meltspun, and photoluminescent POFs to measure their superimposed photoluminescent emission spectra. By varying the concentration of luminophores in yarn and fabric composition, the overall color of the resulting photoluminescent textiles can be tailored by the recapturing of light escaping from individual POFs. The ensuing color space is a mean to address the needs of specific applications, such as decorative elements and textile illumination by UV down-conversion.
