In this project, I investigate the deposition of decorative TaOxNy coatings with controlled color and finishing on flexible substrates, with particular emphasis on fabrics and textiles. The preparation of these films is oriented to three main different markets: i) development of new finishing and color effects for fashion industry; ii) development of textiles with controlled aspect and texture and improved properties for military applications (e.g. camouflage and resistance to aggressive environments); iii) development of textiles with different color and enhanced wear resistance for non-removable textiles (e.g. different types of furniture, or seats for automotive industry).
Although decorative coatings have been studied for rigid substrates, systematized investigation is lacking for flexible ones. The depositions are carried out by magnetron sputtering, which is a technique typically used at industrial levels. Different types of power sources (e.g. r.f. or pulsed d.c.), applied bias, and deposition configurations are being studied in order to obtain films with the abovementioned characteristics. As research system, we have selected tantalum oxynitride (TaOxNy) due to the wide different palette of colors that can be obtained depending on the chemical composition. In this project, we also explore additional possibilities via doping with silver.
