Durable and breathable ZnO/graphene-coated fabrics for enhanced BQR protection
Ferreira, Tânia; Vale, A. Catarina; Gonçalves, Afonso; Pinto, Alexandra C.; Sousa, Diana; Guimarães, Humberto; Moreira, Inês P.; Silva, CarlosThis work developed a new strategy to create active protection against chemical, biological, radiological and nuclear (CBRN) threats, based on polyurethane-based coatings for outer (water and oil-repellency) and inner (CBRN protection) functionalization of fabric. The internal coatings were functionalized with varying concentrations of zinc oxide nanoparticles (ZnO) and/or graphene nanoplatelets (Gf) and carefu...
Comparison of zinc oxide nanoparticle integration into non-woven fabrics using ...
Ferreira, Tânia; Vale, Ana Catarina; Pinto, Alexandra C.; Costa, Rita V.; Pais, Vânia; Sousa, Diana; Gomes, Fernanda Isabel Antunes; Pinto, GraçaThe development of advanced facemasks stands out as a paramount priority in enhancing healthcare preparedness. In this work, different polypropylene non-woven fabrics (NWF) were characterised regarding their structural, physicochemical and comfort-related properties. The selected NWF for the intermediate layer was functionalised with zinc oxide nanoparticles (ZnO NPs) 0.3 and 1.2wt% using three different method...
