Abstract

• Graphene oxide (GO) has been successfully synthesized from graphite powder using the Hummer’s method. In this research, an ecofriendly bionanocomposite material has been fabricated from chitosan (CS)/graphene oxide (GO) by the casting method. The synthesized GO and CSGO were characterized by using FT IR, XRD, FESEM, TG-DTA and UV-Vis spectroscopy. Finally, the size and surface charge of synthesized nanoparticles were determined using the dynamic light scattering (DLS) and zeta potential analyzer, respectively. The results obtained from those different studies revealed that chitosan and graphene oxide could mix with each other homogeneously.
