“…The cellulosic fibers are used to afford high water retention and storage capacities, while the polyolefin fibers are responsible for the high tensile strength, abrasion and solvent resistance [ 8 ]. The nonwoven fabric for wipes is manufactured using spunlace processing technology, where the produced fabric exhibits sufficient softness, flexibility, conformability making it extensively used in wet wipes and medical field compared to the traditional fabrics [ 9 , 10 ].…”

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). We succeeded in preparing disinfectant cellulose-based wipes treated with antimicrobial and antiviral silver nanoparticles to be used for prevention of contamination and transmission of several pathogenic viruses and microbes to human in critical areas such as hospitals and healthcare centers especially coronavirus. In this work, the antimicrobial and antiviral activities of silver nanoparticles (AgNPs) prepared with four different techniques were investigated for the utilization as a disinfectant for cellulose-based wipes. These four methods are namely; 1) trisodium citrate with cotton yarn as a reducing agent, 2) preparing AgNP's using aqueous solution of PVA in the presence of glucose, 3) trisodium citrate with cotton fabric as a reducing agent, and 4) photochemical reaction of polyacrylic acid and silver nitrate solution. Polyester/viscose blended spunlace nonwoven fabrics as cellulose based fabrics were treated with the prepared silver nanoparticles to be used as surfaces disinfection wipes. The properties of the nonwoven fabrics were examined including thickness, tensile strength in dry and wet conditions in both machine direction (MD) and cross-machine direction (CMD), bursting strength, air permeability, water permeability and surface wettability. Characterization of the AgNPs was carried out in terms of UV-VIS spectroscopy, TEM, SEM, and Zeta potential analysis. The assessment of AgNPs active solutions for antimicrobial and antiviral activities was evaluated. The results obtained from the analyses of the AgNPs samples prepared with different techniques showed good uniformity and stability of the particles, as well uniform coating of the AgNPs on the fibers. Additionally, there is a significant effect of the AgNPs preparation method on their disinfectant performance that proved its effectiveness against coronavirus (MERS-CoV), S. aureus and B. subtilis as Gram-positive bacteria, E. coli and P. mirabilis as Gram-negative bacteria, A. niger and C. albicans fungi.

“…With the increasingly severe service conditions of microdevices, the requirements for the performance of the thin-film materials have gradually increased, leading to extensive applications such as nonenzyme glucose sensors [1], highstrength and high-conductivity films [2], antibacterial films [3], semiconductor interconnect [4], wear-resistant films [5], packaging film materials [6] and so on. There are many methods to prepare thin films, such as electrical deposition [7], arc evaporation [8], wet-laid and spunlace process [9], arc discharge [10] and son on [11], but these methods are not suitable for preparing low solid solubility alloy films. Magnetron sputtering has become an important method for preparing thin films due to its fast speed and good uniformity [12].…”

This article studies two different sputtering methods for depositing Ag–Mo and Ag–Zr alloy films on single crystal silicon (Si), flexible polyimide (PI) and soda-lime glass substrates. The phase structure and the surface morphology of the Ag–Mo(Zr) alloy films were characterized by XRD, SEM and EDS. The effects of substrate properties and sputtering methods on the self-grown Ag particles on the Ag–Mo(Zr) alloy films were investigated. As the result of the experiment, nanoscale Ag particles were formed on the surface of Ag–Mo(Zr) alloy films. However, the size and the number of self-formed Ag particles on the Ag–Mo(Zr) alloy film on the PI substrate are significantly different from that on the Si substrate and glass substrate. This outcome is closely related to the different thermal stress evolution behaviors of the alloy films on different substrates during annealing.

“…Graphene oxide sheets [24,25], epoxy functionalized graphene oxide [26], and carboxylic functionalized graphene [27] were grafted on fibers, and found interfacial properties were improved. However, GO modification of fabrics was rarely reported by now, except from literature of Zhang et al [28], who prepared antibacterial fabrics by fixing amino-capped silver nanoparticles (Ag NPs) on surface of fabrics.…”

Interfacial bonding between the fibers and matrix plays a large role in mechanical properties of composites. In this paper, poly(oxypropylene) diamines (D400) and graphene oxide (GO) nanoparticles were grafted on the desized 3D multi axial warp knitted (MWK) glass fiber (GF) fabrics. The surface morphology and functional groups of modified glass fibers were characterized by scanning electron microscopy (SEM) and fourier transform infrared spectra (FT-IR). Out-of-plane compression properties and the failure mechanisms of composites at different temperature were tested and analyzed. The results revealed that GO nanoparticles were successfully grafted on fibers under the synergistic effect of D400. In addition, D400-GO-grafted composite possessed the highest mechanical properties than desized composite and GO-grafted composite. Their strength and modulus were improved by 10.16%, 10.06%, 8.92%, 8.75%, 7.76% and 40.38%, 32.74%, 29.85%, 26.98%, 25.16% compared to those of desized composites at 30∘C, 60∘C, 90∘C, 120∘C, 150∘C, respectively. The damage to D400-GO-grafted composite was yarns fracture accompanied with fibers breakage, matrix cracking, interface debonding. At higher temperature, interlayer slipping with matrix plasticization was the main failure mode.
