The utilisation of polydopamine interlayer to add silver nanoparticles(AgNPs) to PET fabrics

Silver nanoparticles are structures used in many areas such as antibacterial materials, increasing conductivity, wastewater treatment, etc. In recent years, demand for their use in textile products has been increasing. Starting from this point, this study aimed to produce silver nanoparticles on the surface of PET fabric to meet the different properties expected from silver. For this purpose, polydopamine coating was applied to PET fabric by in situ polymerization. Then, fabric structures containing polydopamine and silver nanoparticles were obtained with a reduction reaction of three different molarity silver nitrate salts. The after-washing condition of the fabric with the highest produced amount of silver nanoparticles was examined. Spectrophotometric colour measurement, FT-IR, SEM and EDX techniques were performed. The best results were obtained on the fabric where silver nitrate was applied at 50 mM. The amount of silver nanoparticles in this fabric was measured as 1.35% after washing.
