“…In recent years, a variety of antibacterial agents such as chitosan [5], metal oxides [6], quaternary ammonium salts [7], peptides [8], and guanidine polymers [9] have been used in antibacterial finishing for cotton fabrics. According to the literature [10,11], cationic polymers such as quaternary ammonium salts exhibit excellent bactericidal performance, for example, cotton fabrics treated with quaternary ammonium salt macromolecules can directly kill bacteria by destroying the integrity of cell membranes and impairing the normal respiratory function of bacterial cells [12,13]. However, the cationic antibacterial agents can be inactivated when anionic polymers or additives are encountered [14].…”

Coating a cationic antibacterial layer on the surface of cotton fabric is an effective strategy to provide it with excellent antibacterial properties and to protect humans from bacterial cross-infection. However, washing with anionic detergent will inactivate the cationic antibacterial coating. Although this problem can be solved by increasing the amount of cationic antibacterial coating, excessive cationic antibacterial coating reduces the drapability of cotton fabric and affects the comfort of wearing it. In this study, a coordinated antibacterial coating strategy based on quaternary ammonium salt and a halogenated amine compound was designed. The results show that the antibacterial effect of the modified cotton fabric was significantly improved. In addition, after mechanically washing the fabric 50 times in the presence of anionic detergent, the antibacterial effect against Staphylococcus aureus and Escherichia coli was still more than 95%. Furthermore, the softness of the obtained cotton fabric showed little change compared with the untreated cotton fabric. This easy-to-implement and cost-effective approach, combined with the cationic contact and the release effect of antibacterial agents, can endow cotton textiles with durable antibacterial properties and excellent wearability.

“…For fabric treated with ZnSn(OH) 6 , the bands observed at 778, 850, 1180, and ∼2303 cm –1 may be correlated with the presence of M–OH or M–OH–M groups, i.e., the metal hydroxide bond. 27 The concerned FTIR curve also showed the bending vibration modes of surface −OH groups at 3200 cm –1 , which may be associated with the presence of H-bonding with ZnSn(OH) 6 and the hydroxyl groups of cellulose due to a slight shift of the vibration of −OH. The FTIR curve for the fabric treated with annealed zinc stannate did not show the presence of M–OH or M–OH–M groups on the substrate, whereas the intensity of the M–O–M or the Zn–O–Sn or ZnO or SnO 2 bonds got strengthened, which is visible at 530–591 cm –1 .…”

This study demonstrates the synthesis of nano-zinc stannate and its application as a novel multifunctional finishing agent on cotton fabric. Nano-zinc stannate has been synthesized by the co-precipitation method, and the nanostructures produced have been characterized to investigate their morphology and microstructure by using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction techniques. The synthesized nano-zinc stannate has been applied on cotton fabric and the multifunctional efficacies of the treated fabric, like UV resistance, antibacterial property, self-cleaning, as well as thermal stability, were analyzed. The as-synthesized zinc stannate-treated cotton fabric showed excellent efficiency in self-cleaning, antibacterial property, and flame-resistant action compared to the annealed nano-zinc stannate-treated cotton fabric. It was observed that the ultraviolet protection factor of the treated (annealed zinc stannate-treated) fabric shoot up more than 45 after treatment, and the same fabric showed more than 90% bacterial resistance against both Gram-positive and Gram-negative bacteria. Concerning thermal kinetics, the as-synthesized zinc stannate-treated fabric registered a 39% reduction in the peak heat release rate compared to the untreated cotton fabric, and it also showed catalyzed pyrolysis action and more amount of char mass (30–40% more compared to the control cotton) formation at higher temperature. The self-cleaning efficacy of the treated fabric has been examined against coffee stain and basic methylene blue dye. The treated fabric exhibited a good efficiency in cleaning of stain due to the free-radical scavenging behavior. Finally, it also has been proved that the integration of these nanostructure did not have any detrimental effect on the important physical properties (tensile strength, flexibility, and crease resistance) of the treated fabric.

“…Organic nanomodifications of epoxy resins to impart antimicrobial activity were carried out through different strategies: Blending with intrinsically biocidal polymers such as chitosan [ 70 , 71 ] or copolymerization, with organic moieties able to modify the surface polarity, such as PANI [ 72 ] or non-isocyanate polyurethane [ 73 ], or epoxy polymers made from phenolic branched fatty acids [ 74 , 75 ], or using antibacterial polyether biguanide as a curing agent [ 76 ]. Incorporating into the epoxy resin of quaternary ammonium moieties, which could be formed by (a) direct reaction of NH groups along the epoxy-resin chain with alkyl bromides [ 77 , 78 , 79 ], or preparing hybrid siloxane epoxy coatings by reaction of diamine-bearing epoxy moieties with siloxane-bearing amine groups [ 80 ]; (b) dispersing quaternary ammonium polyethylenimine nanoparticles previously prepared [ 81 ]; (c) preparing polysiloxane quaternary ammonium salts, containing epoxy groups to react with amines [ 82 ] and (d) preparing poly(quaternary ammonium salt-epoxy) grafted on Ce or ZnO nanoparticles [ 83 , 84 ]. Incorporating biocidal compounds, such as triclosan [ 85 ].…”

The main purpose of this work is to provide a comprehensive overview on the preparation of multifunctional epoxies, with improved antimicrobial activity and enhanced mechanical properties through nanomodification. In the first section, we focus on the approaches to achieve antimicrobial activity, as well as on the methods used to evaluate their efficacy against bacteria and fungi. Relevant application examples are also discussed, with particular reference to antifouling and anticorrosion coatings for marine environments, dental applications, antimicrobial fibers and fabrics, and others. Subsequently, we discuss the mechanical behaviors of nanomodified epoxies with improved antimicrobial properties, analyzing the typical damage mechanisms leading to the significant toughening effect of nanomodification. Some examples of mechanical properties of nanomodified polymers are provided. Eventually, the possibility of achieving, at the same time, antimicrobial and mechanical improvement capabilities by nanomodification with nanoclay is discussed, with reference to both nanomodified epoxies and glass/epoxy composite laminates. According to the literature, a nanomodified epoxy can successfully exhibit antibacterial properties, while increasing its fracture toughness, even though its tensile strength may decrease. As for laminates—obtaining antibacterial properties is not followed by improved interlaminar properties.
