Copper nanoparticles on bleached cotton fabric: in situ synthesis and characterization

A coloured polyester fabric with antimicrobial properties conferred by copper nanoparticles

“…In addition to the main peak of the original polyester fabric (2θ = 17-20°), XRD spectra of the treated sample showed characteristic peaks at 2θ angles of 43.6 (111), 50.8 (200) and 74.4° (220), confirming the successful synthesis and deposition of copper nanoparticles on the surface (JCPDS file no.0.4-0836) 19,35,42,43 (Figure 3A).…”

“…The antimicrobial mechanism of copper nanoparticles is related to the bacterial absorbance of copper ions. Moreover, penetration of copper nanoparticles into the cell wall led to the subsequent bacterial death …”

“…They used copper sulphate as a precursor, citric acid as a stabiliser protecting nanoparticles from aggregation and oxidation, and sodium hypophosphite as a reducing agent. The nano copper‐treated fabrics showed excellent antibacterial activities and hydrophobicity . Copper nanoparticles/polystyrene composite was synthesised through the reduction of cupric sulphate with hydrazine in the presence of cetyltrimethylammonium bromide and poly (N‐vinylpyrrolidone).…”

“…The nano copper-treated fabrics showed excellent antibacterial activities and hydrophobicity. 19 Copper nanoparticles/polystyrene composite was synthesised through the reduction of cupric sulphate with hydrazine in the presence of cetyltrimethylammonium bromide and poly (N-vinylpyrrolidone). Thermo-gravimetric analysis showed increased thermal stability of the prepared composite due to the presence of copper nanoparticles.…”
