Abstract
A systematic study of the effect of various types of surfactants (polyethylene glycol, Trinon X-100 and cetyltrimethylammonium bromide) and subsequent annealing on the magnetic ordering and morphology of the nickel ferrite / reduced graphene oxide composite materials has been carried out. Hydrazine hydrate has been used both as an agent to initiate precipitation and as a reducing agent to remove oxygen functionality from the surface of graphene oxide particles. To characterize the material, Mössbauer spectroscopy and nitrogen absorption porosimetry have been used. The obtained result suggests a new way for one-pot synthesis of NiFe2O4/rGO composite materials with controlled magnetic ordering and porous structure.
