“…Different methods can be used to test the antimicrobial properties of nanocomposite functional materials, such as the agar diffusion plate method and the shake flask method [30]. The agar diffusion plate method checks whether the product has antibacterial properties, while the shake flask method gives more accurate antibacterial results.…”

The cost and efficiency of preparing ZnO/Ag composite functional polyester membrane affect their application, for which a rapid microwave-assisted method was studied for coating ZnO/Ag composite nanoparticles on polyester nonwoven. The surface morphology, crystalline structure, and surface chemistry of the uncoated and coated polyester nonwoven was investigated by X-ray diffractometer (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and thermogravimetric (TG), respectively. Washing stability, ultraviolet properties, and antibacterial properties of before and after treatment polyester nonwoven were also investigated. The results indicated that Ag/ZnO composite nanoparticles were successfully deposited on polyester nonwoven surface. The amount of silver nitrate added in reaction has an important effect on the morphology and structure of Ag/ZnO composite on the surface of polyester fiber. The washing experiment results show that the ZnO/Ag composite functional polyester nonwoven fabric prepared by this method exhibits good washing durability after 90 min of washing. The results of UV transmission analysis showed that polyester nonwoven has an obvious increase in ultraviolet resistant properties after Ag/ZnO composite coating. When 0.2 g of silver nitrate was added into 100 mL of the reaction solution, the mean ultraviolet protection factor (UPF) of the treated polyester nonwoven reached a maximum of 219.8. The antibacterial results showed that the coated nonwoven against Escherichia coli and Staphylococcus aureus was about 94.5% and 96.6%, respectively, showing very good antibacterial properties.

“…The selection of stabilizers for silver nanoparticles covers a wide range of various types of simple and complex molecules such as sugars [ 28 ], starch [ 8 ], oligomeric calixarenes [ 34 ], cyclodextrins [ 35 ] or even biological systems [ 5 , 36 , 37 , 38 , 39 ]. A significant number of silver nanoparticle stabilizers are related to the application of polymers such as polystyrene [ 40 ], polyvinylpyrrolidone [ 17 , 22 , 23 , 24 ], polyisopropylacrylamide [ 41 ], hydroxyethylcellulose, polyvinylalcohol [ 23 ], and others.…”

Silver Nanoparticles Stabilised by Cationic Gemini Surfactants with Variable Spacer Length

The present study is focused on the synthesis and investigation of the physicochemical and biological properties of silver nanoparticles stabilized with a series of cationic gemini surfactants having a polymethylene spacer of variable length. UV-VIS spectroscopy, dynamic light scattering, scanning electron microscopy and zeta potential measurements were applied to provide physicochemical characterization of the silver nanoparticles. The mean size values of the nanoparticles were found to be in the 50 to 115 nm range. From the nanoparticle size distributions and scanning electron microscopy images it results that a population of small nanoparticles with the size of several nanometers was confirmed if the nanoparticles were stabilized with gemini molecules with either a short methylene spacer (two or four −CH2− groups) or a long spacer (12 −CH2− groups). The average zeta potential value for silver nanoparticles stabilized with gemini molecules is roughly independent of gemini surfactant spacer length and is approx. +58 mV. An interaction model between silver nanoparticles and gemini molecules which reflects the gained experimental data, is suggested. Microbicidal activity determinations revealed that the silver nanoparticles stabilized with gemini surfactants are more efficient against Gram-negative bacteria and yeasts, which has a direct relation to the interaction mechanism of nanoparticles with the bacterial cell membrane and its structural composition.

“…Silver (Ag) nanoparticles with extraordinary optical, electronic, catalytic, and more importantly antibacterial properties have found great applications in the development of functional polymer nanocomposites [150][151][152]. The widespread use of Ag nanoparticles in toys, clothing, and food packaging products raises serious concerns about their effects on human health and ecosystems.…”

Polymer Composites With Functionalized Nanoparticles

In the past decade, there has been a dramatic increase in the production and application of engineered nanomaterials and their polymeric nanocomposites. This steep increase in the quantities of nanomaterials raises the question of whether the unknown risks of engineered nanoparticles outweigh their benefits and what are the potential risks of such materials on our health and the environment. There are several research results available focusing on the nanomaterials' harmful potential such as the toxicological effect on living organs, and other adverse environmental effects. However, no clear guidelines exist to quantify these effects and to prevent unplanned environmental costs. Therefore, it is necessary for research and industrial communities to engage in nanotoxicological research, risk assessment protocol development, and safe handling guidelines preparation to minimize the environmental consequences of nanoparticles. This chapter will focus on the environmental effects of nanomaterials, nanotoxicology, and their novel and innovative environmentally friendly applications.
