▎ 摘　　要

A simple, cost-effective method to produce strong, single-domain superparamagnetic iron/graphene nano-composites via electrochemical exfoliation/deposition is proposed. The simultaneous graphene exfoliation and Fe deposition could be finely controlled by adding sodium dodecyl sulfate (SDS) as a surfactant in the base liquid. The fabricated composites were characterized through morphological and magnetometric analyses. The adjustable magnetic moment varied from 57.3 to 189.6 emu/g and a correlation between SDS concentration, chemical properties, and surface morphology was observed. The results of this study could promote the synthesis of graphene composites with controllable magnetic properties for practical applications.
