Nano-finishing of cellulose textile materials with copper and copper oxide nanoparticles
Nano-finishing of textile materials with metal and metal oxide nanoparticles has been in the focus of science and textile industry almost two decades. The emergence of bacteria resistance to silver nanoparticles due to over-use, cheaper precursor salts and excellent antimicrobial activity recently brought copper and copper oxide nanoparticles to scientific attention particularly for the utilization in the field of medical textiles. This paper is aimed to give an overview of the latest achievements in the finishing of cellulose fabrics with copper-based nanoparticles. Special emphasis has been given to difficulties met throughout the characterization of such textile nanocomposites caused by the copper instability. In addition the effect of various chemical modifications of cellulose fibers prior to impregnation with copper-based nanoparticles on their binding efficiency was considered. Much attention has been also paid to antimicrobial activity of such textile nanocomposites and the possibility to develop efficient antimicrobial cellulose wound dressings. [GRAPHICS]
