In this work the synergism influence of magnetic calcium ferrite nanoparticles and three morphologies of carbon nanostructures, carbon dot (zero-dimensional), carbon nanotubes (one dimensional) and graphene oxide (two dimensional) on the flame retardancy and thermal stability of the epoxy polymer were investigated. Nanoparticles were synthesized by hydrothermal method in the water as a green solvent. Ultrasonic waves (100-1000W, 1-60 min) were used in all synthesis methods of nanocarbons and magnets as well as polymer nanocomposite as a dispersing tool. The morphology of the nanostructures was investigated by scanning electron microscopy (SEM), phase of the product was approved by X-ray diffraction pattern (XRD) and Fourrier transform infra-red (FT-IR) spectroscopy. Magnetic calcium ferrite has suitable effect as a barrier in front of heating, oxygen and fire. Cone calorimeter, UL-94 test and limiting oxygen index (LOI) tests were used for examination of flame retardancy. Thermal gravimetric (TGA) analysis confirms thermal stability of the products.
