This study aims to conduct the synthesis and characterization of nanohybrid multilayer ZnO-SiO2/Chitosan (NHMZnO-SiO2/Chitosan) using SEM and TEM to show the rod-shape morphology. Furthermore, the compound is used as a textile fiber coating material for anti-bacterial and UV-protected applications. The process was followed by hydrophobization of Dodecyltrietoxysilane (DTS) using a 1,2,3,4-butane tetracarboxylic acid (BTCA) crosslinker. FT-IR showed that the coating of NHM-ZnO-SiO2/Chitosan on textile fibers has covalent ester interactions with the appearance of the C=O stretching functional group at ~1700 cm-1 and each cotton fabric provided different intensity. Meanwhile, SEM showed that the layer has a rough surface, which is associated with the distribution of NHM-ZnOSiO2/Chitosan to create a hydrophobic surface, as evidenced by the water contact angle WCA = 100-119o. Furthermore, UV-DRS analysis was also conducted for UV protection testing and a decrease in the value of Eg = 2.87 eV on textiles coated with NHM-ZnO-SiO2/Chitosan and DTS was obtained. Anti-bacterial activity of uncoated, BTCA - ZnO-SiO2/Chitosan coating, BTCA - ZnO-SiO2/Chitosan coating, and DTS textiles were evaluated against bacterial cells of Staphylococcus epidermidis (37.7 - 47.2) mm and Pseudomonas aeruginosa (42.0 - 49.2) mm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
