“…This was due to using citric acid as a crosslinker, based on the formation of covalent ester interactions between the fibers and ZnO [43] . Furthermore, Rilda et al., (2021) and Ribut et al., (2019), reported that covalent ester interactions were characterized by FT‐IR, due to the absorption band intensity of the C=O group at wave number 1643–1456 cm −1 [39,40] . The intensity of 3324–3414 cm −1 was also the OH strain vibration obtained from the cellulose of the textile materials.…”

The biosynthesis of ZnO is performed through enzymatic mechanisms for controlling the particle size and morphology with using the sol‐gel method. Furthermore, this method utilizes a stabilizer obtained from the cell biomass of Aspergillus niger mold in order to yield homogeneous and consistent products. The evaluation of functional, morphological, and antibacterial activities was carried out at pH 6.0‐13.0. The analysis FT‐IR showed the interaction of hydroxyl groups, aromatic rings, as well as N−H and O−Zn‐O compounds at a wavenumber of 401–584 cm−1. The XRD and SEM characterizations showed that ZnO structure and crystal phase were hexagonal wurtzite at dimensions of 36.2 ‐ 45.4 nm. The differences in pH also influenced the dimensions, morphology, and antimicrobial activity. ZnO with a pH of 8.0 was characterized by FESEM‐EDAX, based on the analysis of morphological uniformity. This characterization obtained rod and cube structures, with atomic ratios of Zn=61.5 % and O=38.5 %. The UV‐DRS spectrum showed that the optical band gap with a value of Eg=3.00–3.11 eV. The differences in morphology further distinguished antibacterial properties on textile fibers, through the use of the Gram ‐ and + bacteria (Pseudomonas aeruginosa and Staphylococcus aureus), with inhibition zones of 17–21 mm and 21–25 mm, respectively. Therefore, ZnO is classified as a very strong antibacterial material than amoxicillin, with an inhibition zone of 13.6 mm.

“…The aim of ZnO coating on textile bres was to modify the function of anti-bacterials. This was due to using citric acid as a crosslinker, based on the formation of covalent ester interactions between the bres and ZnO [42]. Furthermore, reported that covalent ester interactions were characterized by FT-IR, due to the absorption band intensity of the C = O group at wave number 1643-1456 cm − 1 .…”

The biosynthesis of zinc oxide (ZnO) is performed through enzymatic mechanisms, by controlling the particle size and morphology of the compound using the sol-gel method. Furthermore, this method utilizes stabilizer obtained from the cell biomass of Aspergillus niger bacteria, in order to yield homogeneous and consistent products, which corresponds with the XRD outcome that exhibits good crystallinity. The evaluation of functional, morphological, and antibacterial activities was carried out at pH 6.0-13.0, as the prepared samples were characterized by FT-IR. The analysis showed the interaction of hydroxyl groups, aromatic rings, as well as N-H and O-Zn-O compounds at a wavenumber of 401-584 cm−1. The XRD and SEM characterizations showed that the structure and crystal phase of ZnO were hexagonal wurtzite at dimensions of 36.2 - 45.4 nm. The differences in pH also influenced the dimensions, morphology, and antimicrobial activity. ZnO with pH of 8.0 was characterized by FESEM-EDAX, based on the analysis of morphological uniformity. This characterization obtained rod and cube structures, with atomic ratios of Zn = 61.5% and O = 38.5%. The UV-DRS spectrum showed that the optical band gap was not significantly influenced by the pH of the reactant solution, with a value of Eg = 3.00–3.11 eV. The differences in morphology further distinguished anti-bacterial properties on textile fibres, through the use of the Gram-negative and positive bacteria (Pseudomonas aeruginosa and Staphylococcus aureus), with inhibition zones of 17-21 mm and 21-25 mm, respectively. Therefore, ZnO is classified as a very strong antibacterial material compared to amoxicillin, with an inhibition zone of 13.6 mm.

“…However, according to the Cassie–Baxter model, upon reaching a stable superhydrophobic state, the surface is characterized by minimal contact with water droplets owing to air bubbles trapped between the liquid and solid body, which makes it difficult for corrosive agents to contact and reduces the adhesion of contaminants to the material surface. Thus, superhydrophobicity underlies the creation of self-cleaning materials and provides anti-corrosion and anti-biofouling functions [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ].…”

Effect of the Composition of Copolymers Based on Glycidyl Methacrylate and Fluoroalkyl Methacrylates on the Free Energy and Lyophilic Properties of the Modified Surface

et al. 2022

This study proposes to use reactive copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates with a low fluorine content in the monomer unit as agents to reduce the surface free energy (SFE). This work reveals the effect of the structure and composition of copolymers on the SFE and water-repellent properties of these coatings. On a smooth surface, coatings based on copolymers of glycidyl methacrylate and fluoroalkyl methacrylates with fluorine atoms in the monomer unit ranging from three to seven are characterized by SFE values in the range from 25 to 13 mN/m, which is comparable to the values for polyhedral oligomeric silsesquioxanes and perfluoroalkyl acrylates. On textured aluminum surfaces, the obtained coatings provide time-stable superhydrophobic properties with contact angles up to 170° and sliding angles up to 2°. The possibility of using copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates for the creation of self-cleaning polymer coatings is shown.
