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(CH 2 ) 3 N (2 n+1 −1) R 1 (2 n+2 −2) R 2 (2 n+1 ) (I). In this formula, Γ indicates magnetic particles coated with SiO 2 on a surface thereof, the magnetic particles having been modified by a silane coupling agent; (CH 2 ) 3 N (2 n+1 −1) R 1 (2 n+2 −2) is a dendritic group, and R 2 (2 n+1 ) is a lipophilic group, with 0≦n≦100. Further disclosed is a lubricant comprising the magnetic dendrimer compound. |
