Abstract:

Nowadays, textile materials have been widely researched in order to be used in various technological areas. Interdisciplinarity becomes a key factor in order to combine different properties to obtain a multifunctional material. Thus, in this work it is possible to find the mix between the physics and chemistry, amongst the macro, micro and nano. This work presents the results of the application and characterization of nanocoating by physical vapor deposition with pulsed magnetron sputtering (PVD-PMS) and other materials with hydrophobic and photocatalytic behavior. The treated and untreated materials were characterized by several techniques, namely: static and dynamic contact angle, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), scanning electronic microscopy (SEM), transmission electron microscopy TEM, X-ray diffraction (XRD), and atomic force microscopy (AFM). Results support the achievement of a PLA fiber multifunctional with excellent photocatalytic properties (Methylene blue degradation), self cleaning, antibacterial and superhydrophobic. With the optimization of experimental parameters on the PLA fiber using a statistical planning with a response surface methodology was obtained as an efficient plasma treatment process on PLA fibers in order to improve their work of adhesion. In addition, we obtained using the same methodology PLA fibers superhydrophobic and photocatalytic nanocoated with Ag doped TiO2 by PVD pulsed magnetron sputtering (PMS). A contact angle of 170? was obtained using the following parameters: argon flow/oxygen (reactive gas), low-power, time (minutes) and a reverse phase. Besides these, above properties was also developed with PLA fibers, and superhydrophobic/photocatalytic properties
