Development of a textile fabric with antiviral properties impregnated with TiO2-M nanoparticles (M = Ag, Cu, Pt)

Project summary The project involves the development of a self-disinfecting textile that would provide a very high degree of protection for nursing staff. This will involve the impregnation of this tissue with TiO2-M nano-composites, capable of destroying the pathogen. TiO2 doped with a metal (Ag, Cu, Pt, etc.) M-TiO2 is a judicious choice, in this scenario, in view of its chemical inertness, its non-toxicity, and especially its photocatalytic activity in the visible domain. Goal The objective of the ENITA project is to produce textiles with self-disinfecting properties for the manufacture of nursing staff outfits. These products will reduce contamination and therefore reduce spending on medical care. The research aims to understand the mechanism of elimination of germs and viruses in particular by photocatalysis, to better understand the sensitivity of microorganisms to visible light, and to validate this technological approach on COVID 19. At the end of This project, the research teams will have acquired a great deal of knowledge on techniques for depositing TiO2-M nanoparticles on tissues. This will allow the development of disinfectant tissue design modules based on clean technologies, easily usable and at lower costs.
