Different surface functionalized Fe3O4 were added to ethylene vinyl-acetate copolymers (EVA) composite hot melt adhesives (HMAs) to study their influence on the properties of composite HMAs. The adhesion and viscoelastic properties for HMAs were studied using an electromechanical universal testing machine, dynamic mechanical analyzer (DMA) and parallel-plate rheometer, respectively. Orientation structure of HMAs was studied by Infrared dichroism. The results showed that tetraethoxysilane (TEOS) treated Fe3O4 showed better compatibility with EVA composite HMAs, and that TEOS-treated Fe3O4/EVA composite HMAs presented better adhesion property and processing fluidity, compared with bare Fe3O4/EVA composite HMAs and silane coupling agent KH560 treated Fe3O4/EVA composite HMAs.
