“…Tin oxide NPs and vanadium oxide/tin oxide nanocomposites were prepared using a simple sol‐gel method followed by ESP process, using PVA as a carrier. [ 273 ] PVA–SnO 2 nanofibers were characterized by the presence of beads, which were not detectable in PVA‐V 2 O 5 /SnO 2 nanofibers. The produced nanofibers showed interesting thermoelectric properties, with a Seebeck coefficient in the range 20–100 V K −1 evaluated from room temperature to 400K.…”

The recent burst of research on smart materials is a clear evidence of the growing interest of the scientific community, industry, and society in the field.The exploitation of the great potential of stimuli-responsive materials for sensing, actuation, logic, and control applications is favored and supported by new manufacturing technologies, such as electrospinning, that allows to endow smart materials with micro-and nanostructuration, thus opening up additional and unprecedented prospects. In this wide and lively scenario, this article systematically reviews the current advances in the development of thermoactive electrospun fibers and textiles, sorting them, according to their response to the thermal stimulus. Hence, several platforms including thermoresponsive systems, shape memory polymers, thermo-optically responsive systems, phase change materials, thermoelectric materials, and pyroelectric materials, are described and critically discussed. The difference in active species and outputs of the aforementioned categories is highlighted, evidencing the transversal nature of temperature stimulus. Moreover, the potential of novel thermoactive materials are pointed out, revealing how their development could take to utmost interesting achievements.

“…The Seebeck coefficient was measured as 218 μVK −1 at a temperature gradient of 273–282 K and 38.2 μVK −1 near room temperature, as illustrated in Figure 4 e, respectively. Additionally, Subramaniam et al prepared tin oxide nanoparticles and vanadium oxide/tin oxide nanocomposites using a simple sol-gel method, and following that, they fabricated electrospun nanofibers by an electrospinning process [ 87 ]. Moreover, La 0.95 Sr 0.05 CoO 3 nanofibers with diameters in the range of ~35 nm were also successfully prepared by the electrospinning process and exhibited a Seebeck coefficient value of 650 μVK −1 [ 86 ].…”

With the rapid development of wearable electronics, looking for flexible and wearable generators as their self-power systems has proved an extensive task. Fiber-based thermoelectric generators (FTEGs) are promising candidates for these self-powered systems that collect energy from the surrounding environment or human body to sustain wearable electronics. In this work, we overview performances and device structures of state-of-the-art fiber-based thermoelectric materials, including inorganic fibers (e.g., carbon fibers, oxide fibers, and semiconductor fibers), organic fibers, and hybrid fibers. Moreover, potential applications for related thermoelectric devices are discussed, and future developments in fiber-based thermoelectric materials are also briefly expected.

“…24),25) Subramaniam et al 24) showed that gel-derived V 2 O 5 /SnO 2 nanocompos-ites exhibited improved crystallinity, remarkably different surface morphologies, and an increased transmittance range owing to the addition of HCl during the sol-gel process. Subramaniam et al 25) also reported that HCl additives significantly modified the crystalline size, morphology, and optical properties of SnO 2 nanoparticles. These reports indicate that the introduction of acidic additives is an effective method for controlling the chemical and crystal nanostructures of gel-derived materials.…”

The effects of HCl additives (HCl/Si molar ratio = 0.1) on the crystallization behavior, chemical microstructure, and surface morphology of gel-derived lithium disilicate (Li 2 Si 2 O 5 , LD) powders were investigated using sol-gel and heat treatment processes. With HCl additives, the lithium metasilicate (Li 2 SiO 3 , LM) phase preferentially crystallized even at 200 °C for post-heat treated gel-derived LD powders. Moreover, several Li + ions might not be attached to the [SiO 4 ] network but could be located in the residual pores and surfaces in the form of Li(H 2 O) n + ions for pre-heat treated gel-derived LD powders. Meanwhile, Cl ¹ ions could occupy residual pores and surfaces, and be located in the [SiO 4 ] network by forming Si-Cl bonds. In contrast, without HCl additives, only simultaneous crystallization of LM and LD phases appeared at 600 °C. Correspondingly, fewer Li(H 2 O) n + ions were estimated to be located in the residual pores and surfaces, and more Li + ions were located in the [SiO 4 ] network. With HCl additives, the surface morphology of pre-heat treated gel-derived LD powders was characterized by larger particles and smaller voids, in contrast to those without HCl additives, which comprised smaller particles and larger voids. The unique crystallization behavior might be caused by the interactions that occurred between Li(H 2 O) n + ions and Si-OH groups, as well as Cl ¹ ions and Si-Cl bonds in the chemical microstructure of pre-heat treated gel-derived LD powders. These results indicate that HCl additives could effectively modify crystallization behaviors, chemical microstructure, and surface morphologies of gel-derived LD powders, by reacting with LiOH•H 2 O precursors during the sol-gel process.
