Polyurethane nanocomposite impregnated with chitosan-modified graphene oxide as a potential antibacterial wound dressing

In this study, a polyurethane nanocomposite film (PU/CS-GO) was synthesized by incorporating chitosan-modified GO nanosheets (CS-GO) into PU matrices. The successful synthesis of unmodified GO and CS-GO nanosheets was confirmed by FTIR, XRD, Raman, SEM, EDS, and TGA analyses. In comparison with polyurethane nanocomposite containing unmodified graphene oxide (PU/GO), the effect of the modification of GO with chitosan on different properties such...
