Study on Conductive and Antibacterial Properties of Cotton Fabric Modified by Copper Nanoparticles
The copper nanoparticles with a diameter of about 5 nm were prepared by reoxidation reduction method to modify the cotton fabric.The cotton fabric with conductive and antibacterial properties was obtained by loading the copper nanoparticles on the surface of the cotton fiber with fabric finishing meth-od.Then,it was characterized by scanning electron microscopy (SEM),ultraviolet visible spectropho-tometer (UV-Vis)and thermogravimetry (TGA).The results show that the modified cotton fabric (copper nanoparticle/cotton fabric)has excellent antibacterial properties and electrical conductivity. Meanwhile,the samples still have good antibacterial and conductive stability after 180 days of storage. The cotton fabric modified by copper nanoparticles not only broadens the application field of nanoparti-cles,but also provides a new preparation approach and potential research trends for functional textiles of storage stability.
