“…The peak of PAN/nickel nanofibers was assigned at 24.11 ° , which is a peak of PAN nanofibers, and with peaks at 22.99, 33.50, 38.50, 44.74, and 65.26 ° , which are peaks of nickel . The presence of nickel nanoparticles could significantly catalyze the transformation of polymeric nanofibers into a carbon-like graphite structure upon annealing in an argon atmosphere …”

This study describes a sensor based on quartz crystal microbalance (QCM) coated by polyacrylonitrile (PAN) nanofibers containing nickel nanoparticles for methanol gas detection. The PAN/nickel nanofibers composites were made via electrospinning and electrospray methods. The QCM sensors coated with the PAN/nickel nanofiber composite were evaluated for their sensitivities, selectivities, and stabilities. The morphologies and elemental compositions of the sensors were examined using a scanning electron microscope-energy dispersive X-ray. A Fourier Transform Infrared spectrometer was used to investigate the elemental bonds within the nanofiber composites. The QCM sensors coated with PAN/nickel nanofibers offered a high specific surface area to enhance the QCM sensing performance. They exhibited excellent sensing characteristics, including a high sensitivity of 389.8 ± 3.8 Hz/SCCM, response and recovery times of 288 and 251 s, respectively, high selectivity for methanol compared to other gases, a limit of detection (LOD) of about 1.347 SCCM, and good long-term stability. The mechanism of methanol gas adsorption by the PAN/nickel nanofibers can be attributed to intermolecular interactions, such as the Lewis acid–base reaction by PAN nanofibers and hydrogen bonding by nickel nanoparticles. The results suggest that QCM-coated PAN/nickel nanofiber composites show great potential for the design of highly sensitive and selective methanol gas sensors.

Electrospun Materials Based on Polymer and Biopolymer Blends—A Review

2023

View full text Add to dashboard Cite

This review covers recent developments and progress in polymer and biopolymer blending and material preparation by electrospinning. Electrospinning is a technique that is used to produce nanofibers to improve the quality of membranes. Electrospun nanofibers are highly applicable in biomedical sciences, supercapacitors, and in water treatment following metal ion adsorption. The key affecting factors of electrospinning have been checked in the literature to obtain optimal conditions of the electrospinning process. Future research directions and outlooks have been suggested to think about innovative ideas for research in this field.

“…Some biopolymers can also be good sacricial pore forming agents, as it was demonstrated recently on high amylose starch. 91,92 High amylose starch has a melting point around 280 °C, and starts decomposing soon aer it melts from about 300 °C. 91 When blended with polyacrylonitrile for the preparation of porous carbon nanobers, a specic surface area as high as ∼1200 m 2 g −1 could be reached with micro-mesoporous hierarchical structure.…”
