Recently the world has encountered a number of viruses, and various efforts are being made to overcome them, such as searching for substances with antiviral properties. Among metals known to have antibacterial and antiviral properties, copper is getting a lot of attention because it is cost-effective and readily available. When copper is nano-sized, it has a completely different size and shape, and new properties appear. From these properties, copper nanoparticles showing excellent efficacy in the antiviral test using the MDCK cell line were prepared, and the antiviral test was performed by applying them to the film coating. Copper nanoparticles used for film coating had a size of about 150nm and a relatively constant spherical shape. When manufacturing copper nanoparticles, ethylene glycol and distilled water were used as solvents, CuSO4·5H2O as a precursor, a dispersant, and a stabilizer were used, and they were manufactured in an environmentally friendly process through electron-beam irradiation. Copper nanoparticles were characterized by using SEM, TEM, EDS, DLS, and XRD for size, shape and composition. Copper nanoparticles which have antiviral properties are expected to be applicable not only to film coatings but also to paints, indoors and outdoors, where people can reach.
