Abstract

Physical Vapor Deposition - Plasma Enhanced Chemical Vapor Deposition (PVD-PECVD) systems are used exclusively for deposition and doping of carbonaceous films. However, this technique presents promising characteristics for the deposition of silver nanoparticles (Ag-NPs) on textiles, which meet the industrial demand for a more versatile and efficient methodology than the Magnetron Sputtering (MS) technique. In this regard, cotton textiles were coated with Ag-NP films produced by PVD-PECVD, and compared in terms of technical Physical vapor deposition - plasma enhanced chemical vapor deposition (PVD-PECVD) system has been used exclusively for deposition and doping of carbonaceous films [silver nanoparticles (Ag-NPs)] on cotton fabrics and the findings are compared, in terms of technical efficiency and microbial inhibition, with those of the magnetron sputtering (MS) technique. It is found that the proposed technique presents promising characteristics for the deposition of silver nanoparticles (Ag-NPs) on textiles, which meet the industrial demand.efficiency and microbial inhibition, with findings in the literature for the MS technique.
