Abstract

Nanofibers with inorganic nanoparticles are novel hybrid nanocomposites that have great potential in various areas.

Reducing the resistance for the use of electrochemical impedance spectroscopy analysis in materials chemistry

“…9,18,45,48,49 The CPE is impacted by surface roughness, chemical inhomogeneity, and a heterogeneous electrode-electrolyte interface caused by ion adsorption. 50 The magnitude of the circuit elements can provide unique information about the conductive material under investigation, such as estimate the effectiveness of electrode material enhancements, 21,22,51 indicate the presence and magnitude of the corrosion processes, 26,52,53 or evaluate the suitability of the experimental operating conditions and design. 28 For example, EIS data was recently used to probe the extent of the degradation of electrochromic devices created with different CEs.…”

Cellulose–Silver Composites Materials: Preparation and Applications

“…San Keskin et al employed the electrospinning method for the preparation of cellulose acetate nanofibers (CA-Nf) loaded with biogenic silver nanoparticles using Lysinibacillus sp. NOSK cell-free extract as a reducing agent for the silver nanoparticle production [ 98 ]. The aqueous CA solution was dissolved in DCM/MetOH (4/1, v / v ) mixed solution to prepare neat non-porous CA nanofibers.…”

“…A novel electrospun fiber mat composition [CA/PEG/AgNPs] with improved functional and antibacterial properties was created by reducing AgNPs in situ via a chemical reaction with the electrospinning solvent 2:1 acetone/DMAc and stabilizing them with PEG to prevent particle agglomeration. The fiber mat containing PEG showed increased swellability higher than without PEG [ 98 ]. Wang et al used the electrospinning method to incorporate CMC/PEO nanofibers with AgNPs, and no other reducing agent was needed.…”

Green Fabrication of Anticorrosive, Antibacterial, and SERS Active Nanohybrid Coatings by Dual-Spinneret Electrospinning

“…15,16 In addition, the coatings with embedded biocides (i.e., biogenic AgNPs) can improve the antibacterial properties and be used as an effective and environmentally benign MIC protection strategy. 17 Herein, we developed anticorrosive, antimicrobial, and surface-enhanced Raman scattering (SERS) active nanohybrid coatings[(polymer/zeolite/oligosaccharides/biogenic silver nanoparticles (AgNPs)] as a corrosion protection layer via a simple dual-spinneret electrospinning technique. In the first spinneret, the polysulfone (PSU) nanofibers, which serve as both barriers to the corrosive environment and the carriers of zeolites, were directly deposited on the metal surface.…”

“…Zeolites, which are crystalline aluminosilicates with nanoporous structure, have been evaluated for applications as environmentally friendly anti-corrosion coatings due to their high-surface area, thermal and chemical stability, and nontoxic properties compared to conventional chromate-based coatings. , In addition, the coatings with embedded biocides (i.e., biogenic AgNPs) can improve the antibacterial properties and be used as an effective and environmentally benign MIC protection strategy …”
