“…Moreover, this loss could be attributed to the peeling of some rGO sheets from the clusters due to the loss of the oxygenated functional groups. 28 It is noticeable that the mass percentages of Ag and O in Ag@GO-SA/PP/HNO 3 -IP are much lower than those of Ag@GO/PP/HNO 3 -IP and Ag@rGO/PP/HNO 3 -IP. The addition of long carbon chains of SA onto Ag@GO sheets has increased the mass of the fiber as well as the number of C while the amount of O and Ag molecules remains the same.…”

Herein, poly(propylene) (PP) was hydrophilized with oxidating agents and solvents, followed by dip‐coating with silver nanoparticles anchored GO sheets (Ag@GO) prepared by the in‐situ method as reported in our previous study to obtain silver@graphene oxide‐coated poly(propylene) (Ag@GO/PP). The impact of the modifying agents, dipping times, and coating concentrations on the antibacterial activities were studied accordingly via the inhibition zone method. The fabrics were re‐hydrophobized with the reduction of Ag@GO and the functionalization with stearic acid (SA) to form silver@reduced graphene oxide‐coated poly(propylene) (Ag@rGO/PP) and silver@graphene oxide/SA‐coated poly(propylene) (Ag@rGO‐SA/PP), respectively. Characterization of pretreated and modified PP samples was carried out by various modern analysis methods. Simultaneously, the cytotoxicity of the active layers, the release of Ag+ ions, and durability after washing were also investigated. The obtained results representing PP fabrics pretreated with HNO3/isopropanol and dipped in Ag@GO concentration of 2 g/L four times prove a sufficient approach for improving hydrophilization and bio‐compatibility for the PP samples. The fabrics greatly show an impressive interaction with precursors, mostly high antibacterial activity even after four washing cycles via appropriate releasing of Ag+ to ensure the safety in usage. They further suggest that the prepared fabrics could be utilized for actual application as a face mask.

“…The influence of maintenance treatments on the reduction of the durability of hydrophobic finishes was also confirmed by Gargoubi et al [ 11 ], Schellenberger et al [ 12 ], Kowalski et al [ 22 ], Solomon [ 23 ], Yurdakul et al [ 24 ], Shi et al [ 25 ], Deng et al [ 26 ], and Ivanova and Zaretskaya [ 27 ], who observed that the deterioration of water-repellent properties of materials with hydrophobic finishes increases with the number of washing cycles. Additionally, it was shown that the durability of water-repellent properties of materials depends on the type of laundry detergent used [ 28 , 29 ].…”

“…Depending on the method adopted for testing the water repellency of materials, the conclusions drawn from the results obtained may differ significantly. Solomon [ 23 ], Yurdakul et al [ 24 ], Kowalski and Salerno-Kochan [ 28 ], and Brooks [ 30 ], who evaluated the durability of hydrophobic finishes using the spray test method, showed a significant decrease in the water-repellent properties of textiles after washing processes. In contrast, Shi et al [ 25 ], Deng et al [ 26 ], and Ivanova and Zaretskaya [ 27 ], who used the contact angle measurement method to evaluate the hydrophobic properties of materials after washing processes, showed a high durability of the tested hydrophobic finishes.…”

The aim of the research was to evaluate the changes in the surface properties of five functional clothing materials with water-repellent finishes (including PFC-free finish) after 1, 5, and 10 washes with three detergents. A new approach to the interpretation of the water-repellent properties of textile materials is presented, based on two techniques, i.e., the spray test method and contact angle measurements. The results showed that washing materials with hydrophobic finishes can cause significant changes in their properties, which are mainly dependent on the composition and structure of the material, as well as the type of hydrophobic finish. The PFC-free finish is the least resistant to washing. For all materials with PFC finishes, the water repellency depends on the fluorine content on the surface and fabric topography. It was also found that increasing washing frequency resulted in a gradual decrease in water repellency. The loss of water repellency below an acceptable level (Grade 3) occurred after the fifth washing for all materials. Significant differences in the interpretation of the results of the spray test and contact angle measurements were observed. Using these methods separately provides information on the changes in the surface properties of the tested materials; however, their parallel application allows for obtaining complementary data, which is important for the proper interpretation of results.

“…In the case of biofouling the most commonly used solution is the introduction of silver nanoparticles into membranes or into a separate system [46,47]. These multiple solutions show that the problem is not yet fully solved, especially in particular cases where the flow regime cannot be imposed [48][49][50][51][52].…”

Improving the Performance of Composite Hollow Fiber Membranes with Magnetic Field Generated Convection Application on pH Correction

The membranes and membrane processes have succeeded in the transition from major technological and biomedical applications to domestic applications: water recycling in washing machines, recycling of used cooking oil, recovery of gasoline vapors in the pumping stations or enrichment of air with oxygen. In this paper, the neutralization of condensation water and the retention of aluminum from thermal power plants is studied using ethylene propylene diene monomer sulfonated (EPDM-S) membranes containing magnetic particles impregnated in a microporous propylene hollow fiber (I-PPM) matrix. The obtained membranes were characterized from the morphological and structural points of view, using scanning electron microscopy (SEM), high resolution SEM (HR-SEM), energy dispersive spectroscopy analysis (EDAX) and thermal gravimetric analyzer. The process performances (flow, selectivity) were studied using a variable magnetic field generated by electric coils. The results show the possibility of correcting the pH and removing aluminum ions from the condensation water of heating plants, during a winter period, without the intervention of any operator for the maintenance of the process. The pH was raised from an acidic one (2–4), to a slightly basic one (8–8.5), and the concentration of aluminum ions was lowered to the level allowed for discharge. Magnetic convection of the permeation module improves the pH correction process, but especially prevents the deposition of aluminum hydroxide on hollow fibers membranes.
