Abstract: NPs were synthesized using a very straightforward precipitation method. The successful synthesis was confirmed by Scanning Transmission Electron Microscopy (STEM) and Attenuated Total Reflectance-Fourier-Transform Infrared Spectroscopy (ATR-FTIR). The functionalization of the fabrics with the NPs and the nanofibers doped with NPs was proved by Field Emission Scanning Electron Microscopy (FESEM), ATR-FTIR, and Ground-State Diffuse Reflectance (GSDR). The developed samples presented antibacterial activity against Staphylococcus aureus (ATCC 6538) and Escherichia coli (ATCC 434), reaching values of 99.97 and 100.0 %, respectively. The degradation of methylene blue (MB) and dimethyl methylphosphonate (DMMP) was evaluated. The best samples were able to decompose 97.82 % of DMMP. The wash durability of the nanocoating was also tested. The developed fibrous structures show great potential for personal protection applications.
