Sandwich-Structured Coating for Ultraviolet Protection and Thermal Management Applications
Ugur Kartal, Metin Yurddaskal
TL;DR
A new sandwich-structured coating on polyester fabric provides UV protection and thermal management, making it suitable for protective textiles.
Contribution
The study introduces a TiO2/Cu–Al/TiO2 multilayer coating with UV shielding and thermal barrier properties on polyester fabric.
Findings
The TCAT coating on polyester fabric achieved near-zero UV transmittance and suppressed light penetration in the visible to near-infrared range.
Thermal imaging showed reduced surface temperature for coated fabrics, indicating potential thermal shielding effects.
The coating retained moderate visible transmittance on glass while forming an optically dense barrier on fabric.
Abstract
During the day, exposure to UV radiation poses risks to human health, while managing heat exchange is important for comfort in protective textiles. Recently, infrared-reflective materials have attracted attention, particularly for reducing the infrared transmission and moderating the thermal emission. In this study, titanium dioxide/copper–aluminum/titanium dioxide (TiO2/Cu–Al/TiO2, TCAT) sandwich-structured coatings were deposited on polyester fabric using magnetron sputtering. Deposition times (40 and 90 s) were varied to adjust Al and Cu layer thicknesses between 20 and 55 nm, and the resulting films were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, UV–vis spectroscopy, and thermal imaging. The coatings retained moderate visible transmittance on glass, whereas on woven polyester fabric, they formed an optically dense barrier with…
