Ag Doping and rGO Coupling of TiO₂ within Polysiloxane Matrix for the Ecofriendly Development of High-Performance Cotton Fabric

In this work, TiO 2 was applied to cotton fabric by a sol–gel-hydrothermal process. A combination of 3-(trihydroxysilyl) propyl methylphosphonate monosodium salt solution (TPMP) and (3-aminopropyl)triethoxysilane (APTES) was used as a matrix to enhance the interfacial interaction between TiO 2 and surface of the cotton fibres. During the hydrothermal treatment, silver nitrate (AgNO 3 ) or reduced graphene oxide (rGO) were added to produce Ag-doped TiO 2 - or rGO-coupled TiO 2 -coated textiles. The successful application of all investigated components on cotton fabric was confirmed by the analysis of SEM and EDS. The results of UPF determination and self-cleaning activity showed excellent performance of both studied nanocomposite coatings, whereas the use of rGO proved to be better than Ag.
