“…5, the FTIR spectra of TiO 2 -NPs@PU and TiO 2 -NTs@PU were primarily composed of the peaks of TiO 2 photocatalysts and PU foam. In addition, a shift to the high wavenumber in the FTIR spectra of TiO 2 -NPs@PU and TiO 2 -NTs@PU was observed owing to the hydrogen bonds formed between TiO 2 photocatalysts and PU foam [44]. Furthermore, some peaks were observed at about 790-1000 cm − 1 in the FTIR spectra of TiO 2 -NPs@PU and TiO 2 -NTs@PU, which can be attributed to the vibration of Ti-O-C [28,45,46].…”

Low-melting-point metal alloys (LMMAs) have great potential for application in soft sensors. However, the high cost limits the application of gallium-based liquid metals. In this paper, LMMA In3SnBi has been designed and prepared through a facile melt-mixing process followed by an ultrasonic dispersion technique. To overcome the fragility of low-melting-point alloys, flexible electrospun polyurethane (PU) matrix is used as structural support. When used as a sensor, the composite film exhibits a response time of 54.37 ms within a strain range of 15%. In addition, the composite film exhibits self-healing properties, and cracks generated by cyclic stretching can be repaired through a hot-pressing process. The current work presents a versatile fabrication strategy for LMMA-based flexible sensors, which holds great promise in the field of wearable electronic devices.

“…Among these nanoparticles, TiO 2 stands out for its remarkable characteristics, such as high refractive index, excellent UV resistance, and photocatalytic activity, making it particularly valuable in electrospinning applications [34,35]. One of the primary benefits of integrating TiO 2 nanoparticles into electrospun fibers is improved mechanical properties [14,36,37]. TiO 2 nanoparticles enhance the tensile strength and modulus of the polymer matrix, resulting in more robust and durable nanofibers.…”

In this study, the functionality of polylactic acid (PLA) nanofibers was enhanced by blending polycaprolactone (PCL) and adding titanium dioxide (Figure) nanoparticles. Various concentrations of TiO2 nanoparticles, ranging from 1 to 7 wt%, were added to the PLA nanofibers. Optimal dispersion was observed at 3 wt% TiO2, resulting in 493.64 ± 129.78 nm fiber sizes. Blending PLA with PCL in a 1:1 ratio yielded fibers with an average diameter of 513.20 ± 64.85 nm. The addition of TiO2 nanoparticles into the PLA/PCL blends increased fiber pore area due to the larger fiber size. Mechanical testing indicated that adding TiO2 nanoparticles enhanced the strength of the nanofibers slightly, while ductility increased significantly. The results for the water uptake behavior of the fibers showed that TiO2 NP addition improved the water absorption. Antibacterial activity was evaluated against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) using the agar disk diffusion method. TiO2 NPs added PLA and PLA/PCL nanofibers demonstrated inhibition zones of 10.46 ± 1.03 mm and 19.30 ± 1.47 mm against S. aureus, and 13.33 ± 1.15 mm and 21.71 ± 1.74 mm against E. coli, respectively.
