▎ 摘  要

By taking advantage of design and construction of strong graphen-ematrix interfaces, a ternary nanoparticle (GNS-Fe3O4@PZM) consisting of graphene, Fe3O4 nanoparticles and highly cross-linked polyphosphazene has been synthesized via a two-stage process consisting of co-precipitation and precipitation polymerization. And then the bismaleimide (BMI) matrix composites with aligned GNS-Fe3O4@PZM are fabricated under a magnetic field to take full advantage of the tribological properties of graphene. Characterization results reveal that the 0.8 wt% aligned GNS-Fe3O4@PZM/BMI composite has the lowest friction coefficient and volume wear rate compared with non-aligned GNS-Fe3O4@PZM/BMI and aligned GNS-Fe3O4/BMI composites under all the test conditions. In addition, the aligned GNS-Fe3O4@PZM/BMI also shows superior mechanical properties and thermal stability. The excellent properties of aligned GNS-Fe3O4@PZM/BMI result from uniformly distribution and parallel alignment of graphene in the BMI matrix, as well as good interface interaction between GNS-Fe3O4@PZM and BMI matrix.
