epoxy resin containing carbon nanotubes and nickel ferrite nanoparticles to increase thermal stability and flame retardancy

In this work thermal stability and flame-retardancy of epoxy polymer have been considered. nickel ferrite nanoparticles were fabricated using ultra-sonic waves and these nanoparticles with modified carbon nanotubes were added to epoxy resin. in order to study size and morphology of the produced samples scanning electron microscopy (sem), was studied. also for better investigation of shape, particle and nanotubes size transmission electron microscope (tem) was applied. x-ray diffraction pattern illustrate phase of the nickel ferrite product, fourier transform infra-red (ft-ir) confirm purity and bonds in the compound. thermal gravimetric analysis approve improving thermal stability of the product in the presence of modified carbon nano tubes. also ul-94 test confirm increasing flame retardancy of the product by addition of nickel ferrite nanoparticles. this magnetic char as a barrier decrease reaching of oxygen, flame and heating to the protected under side polymer.
