Abstract:

In order to study the effect of polyester fabric structure on the morphology and performance of nanocomposite film deposited on the surface of fabrics, direct current (DC) and radio frequency (RF)co-sputtering methods were used to prepare Ag/ZnO films with knitted polyester fabrics of different structures as the substrate and metallic silver and zinc oxide as targets respectively. By using field emission scanning electron microscope, X-ray diffractometer, photoelectron spectrometer, computer measurement and matching system, ultraviolet transmittance tester, electromagnetic radiation tester, the films were evaluated in terms of surface structure, color analysis, UV protection and electromagnetic shielding performance. The experimental results show that the particle size of the film on the surface of the nonwoven fabric is more uniform, the surface of the woven fabric is less smooth, the surface particle of the knitted fabric is smaller, and some particle amalgamation are found. Diffraction peaks with Ag are more obvious, but ZnO still exists in amorphous form. After depositing Ag/ZnO film on the surface of knitted fabric, its brightness is the lowest and the color is dark. The samples with nonwoven fabric as substrate demonstrate the most obvious ultraviolet resistance and electromagnetic shielding effect.
