Textile substrates offer relatively high surface area, flexibility, and low cost for catalysis, flexible/wearable electronics, and energy storage applications. By their nature, many textile materials cannot offer much for these trending applications; therefore, they require modifications. Atomic layer deposition (ALD) is one of the prominent techniques that can modify every fiber in a textile material at relatively low temperatures. In this study, organic and glass textile substrates are deposited with ZnO thin films via ALD, and the Ag nanoparticles are deposited on top of the films via the photochemical process. Metal oxide semiconductors such as ZnO can absorb the photon energy to generate radical species that can stimulate reduction and oxidation reactions. It is possible to deposit metal species on a photocatalytic material such as ZnO using the reduction route. Ag nanoparticles obtained on the fibers showed different structures depending on the metal salt used, the pH of the system, or the presence of auxiliary chemicals. The structure of the materials is investigated via SEM, EDS, and XRD analysis. Furthermore, the materials' electrical and thermal conductivity is investigated for possible composite applications.
