SELF-ASSEMBLY OF SURFACTANTS IN THE PRESENCE OF SILVERNANOPARTICLES
The use of silver nanoparticles (Ag NPs) in consumer products, such as sportswear, washing machines and medical devices, has rapidly increased on the market due to their antibacterial properties. An important source of Ag NPs to the environment is from cleaning of Ag NP impregnated textile, where they come in contact with surfactants in the laundry circle (notably anionic sodium dodecylbenzenesulfonate (LAS), cationic dodecyltrimethylammoniumchloride (DTAC) and nonionic Berol 266 (Berol)). We have previously studied the surfactant–Ag NP interactions by means of dynamic light scattering, Raman spectroscopy, zeta potential, and Quartz Crystal Microbalanceby, and the results indicate formation of self-assembled surfactant structures in the proximity of Ag NPs. Our interest in using small-angle neutron scattering is to characterize the structure of those self-assembled aggregates formed in presence of differently charged Ag NPs.
