چکیده مقاله:
Recently, use of magnetic graphene nanocomposites (MGNs) has been emerged assignificant way in targeted drug delivery because of their promising physiochemical andmagnetic properties [1]. Fabrication of such materials with large magnetic moment that needlower external magnetic field for stimulation is important [2]. In this work, we synthesisedsuperparamagnetic graphene nanocomposites by electrochemical method using different molarratios of Sodium dodecyl sulfate (SDS) as surfactant. With the addition of SDS we couldproduce uniform superparamagnetic graphene nanocomposites with large magnetic moment andhigh dispersibility [3]. The presented materials were characterized by XRD, FTIR, EDX andVSM. Also their morphologies were investigated by FESEM and SEM. Finally we found thatmagnetic properties of MGNs have not linear relation with surfactant’s concentration afterexamination of different concentration of surfactant. The results indicate that the optimumconcentration of surfactant to be 0.005 gr.lit-1 SDS to achieve a magnetic saturation as large as189.63 emu/gr.
