文摘

Aluminum doped zinc oxide (AZO) film was deposited onto a polyester fabric by magnetron sputtering. The coated fabric samples were then systematically investigated by X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy and Fourier transform infrared spectroscopy. The thickness of the AZO film on fabric samples was also evaluated, as well as the water repellency, ultraviolet protection factor (UPF) and infrared emissivity. The results showed that the AZO coated fabric presented higher water repellency with a contact angle (CA) of 146° and substantial reduction of ultraviolet transmittance with a UPF value of 362. The infrared emissivity of the AZO coated polyester fabric was reduced to 0.916 in comparison to the untreated fabric of 0.979, when the thickness of the AZO coating was 450 nm.
