In the present study Schiff bases of Carboxymethyl Chitosan/p-dimethylamino benzaldehyde Schiff base (CMC-SB) and its copper complex (CMC-SB-Cu) were prepared and characterized by FTIR, XRD and SEM studies. The results show the formation of Schiff bases with the amine of carboxymethyl chitosan and aldehyde. The copper (II) metal complexes were prepared by sol gel method. The complexes were again characterized by FTIR, XRD and SEM studies. The antioxidant activities of the prepared CMC derivatives were studied by DPPH studies. From the results it can be concluded that the complexes are less toxic and have good antioxidant activity. The results are discussed.
