Microstructure, near infrared reflectance, and surface temperature of Ti-O coated polyethylene terephthalate fabrics prepared by roll-to-roll high power impulse magnetron sputtering system

Among numerous coating techniques used to deposit Ti-O thin films, high power impulse magnetron sputtering (HIPIMS) has attracted a great deal of attention recently due to its high plasma density, that forms a strongly adhered film at a relatively low temperature. In this study, a roll-to-roll high power impulse magnetron sputtering (R2R-HIPIMS) system to produce multifunctional Ti-O coatings on polyethylene terephthalate (PET) fabric substrate has been used, which takes advantage of large-scale production and high-quality coatings. Microstructure, NIR reflectance, and surface temperature of Ti-O coated PET fabrics have been investigated. Results indicate that the R2R-HIPIMS is a promising sputtering process in fabricating Ti-O coatings for applications in functional textiles.
