Description

The study of antimicrobial fabrics with silver nanoparticles (AgNPs) incorporation has shown excellent properties in medical, pharmaceutical, cosmetics and electronics applications due to their formidable action against pathogens, preventing and treating infections.[1] The high surface-to-volume ratio from AgNPs promotes an easy release of silver ion, responsible for the antimicrobial effect.[2] The most traditional method for nanoparticles deposition onto fabrics is the pad-dry-cure technique.[3] Other methods were developed such as dip coating, electrochemical methods and layer-by-layer depositions.[4-6]. However, the major methods have several limitations for noble metals. In this work, several methods for AgNPs deposition on Dielectric barrier discharge (DBD) plasma pre-treated polyamide 6,6 (PA66) were tested for the production of durable antibacterial textiles. DBD plasma was previously used for surface modification to increase surface energy through the introduction of polar groups altering wettability and roughness.[7] However, the study for an efficient deposition methods after plasma treatment was disregarded. SEM, XPS, cytotoxicity and antimicrobial tests were performed to evaluate the different deposition methods.
