  Abstract

Atomic layer deposition is a low-temperature conformal thin film formation technique that can modify materials to create functional surfaces. In this study, ALD coatings onto fibrous structures were used to synthesize the Ag nanoparticles on the fibers, which can be used for a wide variety of applications. During the treatment, cotton fibers were coated with 20 nm thick ZnO films via ALD, and Ag nanoparticles were deposited on top using a photochemical approach. As the samples were analyzed with FESEM images, the ZnO film coatings were found conformal and crystalline with evident grains on the fiber surfaces. After the photodeposition process, the Ag particles were also grown conformal on ALD films with flake-like morphology. XRD analysis showed ZnO and Ag crystalline peaks were visible for the corresponding samples. XPS analysis showed Ag deposition onto untreated cotton is due to ionic interactions whereas the presence of ZnO enables metallic nanoparticles formation. Antibacterial activity of the coating materials was tested using ISO 20645 and AATCC 100 standards, indicating that a high amount of silver present on the surface of the fibers created an uninhabitable environment for the S. aureus and E. coli bacteria.
