“…Inspired by these findings, this work presents an evaluation of the morphological, structural and optical properties of cotton samples in parallel with those of leather samples using TiO 2 -SiO 2 -reduced graphene oxide nanopowders in organic dispersion media, organosilicon compounds, plant-based polymers and biodegradable solvent as coating formulations and CAPP treatments, using Ar and Ar/O 3 as gas plasma. Many papers [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ] have already reported the modification of textiles, but only some of the literature’s data report about improved leather surfaces [ 25 , 26 , 27 , 28 ] using TiO 2 /SiO 2 , TiO 2 /graphene oxide and SiO 2 /graphene oxide. Moreover, we have found only one prior report on TiO 2 /SiO 2 /GO nanocomposites deposited onto the polyester/cotton fabric surface in order to impart a self-cleaning function [ 29 ] as well as on the combination of atmospheric pressure plasma treatment and nano-finishing treatment using a TiO 2 -SiO 2 nanocomposite on the surface properties of leather [ 30 ].…”
