Abstract

Disclosed is a magnetic dendrimer compound and a method for preparing the magnetic dendrimer compound, the molecular formula of which is shown in formula (I): Γ(CH2)3N(2n+1−1)R1(2n+2−2)R2(2n+1)(I). In this formula, Γ indicates magnetic particles coated with SiO2 on a surface thereof, the magnetic particles having been modified by a silane coupling agent; (CH2)3N(2n+1−1)R1(2n+2−2) is a dendritic group, and R2(2n+1) is a lipophilic group, with 0≦n≦100. Further disclosed is a lubricant comprising the magnetic dendrimer compound.
