Abstract
Silver/titanium dioxide (Ag/TiO^sub 2^) composite films were successfully deposited on polyester fabric by using direct current (DC) magnetron sputtering and radiofrequency (RF) magnetron reaction sputtering techniques with pure Ag and Ti targets. Atomic force microscope and X-ray photoelectron spectroscopy were used to examine the structure and composition of Ag/TiO^sub 2^ composite films. Anti-ultraviolet properties and antistatic properties of the Ag/TiO^sub 2^ coated fabric were investigated, and structural color of the Ag/TiO^sub 2^ coated fabric was also analyzed. The experimental results showed that the composite films deposited on textile substrates were even and dense. It was also found that Ag in Ag/TiO^sub 2^ composite films was elemental silver, but Ti in Ag/TiO^sub 2^ composite films was completely oxidized, and existed in TiO^sub 2^ form. Compared with the original fabric samples, anti-ultraviolet properties and antistatic properties of the fabrics deposited with Ag/TiO^sub 2^ composite films were improved significantly; meanwhile, different structural colors of the coated fabrics were generated.

With the development of science and technology and the improvements in living standards, people are paying increasing attention to the demand for better properties of functional textiles, such as safety, comfort, etc. Multifunctional finishing is the technology that blends two or more functional properties in a textile material to improve product quality and add value.1 In order to achieve the goal of multifunctional properties, various advanced and innovative technologies have been applied to functional textiles.2-4 In recent years, methods of functional finishing have mainly included the use of functional finishing agents, new functional fibers, and the magnetron sputtering technique, as well as some other methods.
Magnetron sputtering technology possesses many advantages, such as a uniform film thickness, many sputtering materials, strong binding strength between deposited film and substrate, environmental protection, and so on. Magnetron sputtering technology can prepare super-hard films, corrosion and friction resistant films, superconducting films, magnetic films, optical films, and other special films. It has been considered as a very effective deposition method of thin film.5-13
In this work, metallic silver (Ag) and titanium dioxide (TiO2) films were deposited on a textile substrate by magnetron sputtering technology. Silver has excellent electrical, optical, and chemical properties, whereas titanium dioxide has high photocatalytic activity,...
