摘要: Abstract In this work, we report a simple strategy for improving the mechanical and thermal performances of epoxy resin using novel magnetic composite nanofluid as filler. The nanofluid, composed multicomponent core graphene oxide (GO)/carbon nanotube (MWCNTs)/Fe3O4 (GMF) shell polyether, is fabricated via combination ultrasonic assisted chemical coprecipitation process post-modification. Subsequently, epoxy/GMF prepared under field, in which GMF nanoparticles are well dispersed matrix without obviously agglomeration exhibit directional arrangement along field. i.e., GO sheets induced to align parallel field direction, MWCNTs uniformly on with orientation Fe3O4 further encapsulated GO/MWCNTs composites form core. degree enhanced an increase strength. results indicate that Tg material increases by 17 °C increasing content. Moreover, impact bending apparently 136.5% 30.9% 1.5 wt% oriented at 0.6 T. addition, exhibits anisotropy conductivity.
