Fabrication of polymeric shields to attenuation ionizing radiation and a flame retardant supported by nano-bismuth oxide prepared by co-deposition

The results of the preparation of protective shields from ionizing radiation, flame retardant from pure epoxy supported by nano-bismuth oxide, show that the protective shields supported by nanoparticles improve the attenuation properties, the thermal stability, the flame retardancy and mechanical properties. Also, the polymeric shield supported by Bi₂O₃ (Na₂CO₃) retardant the flame much better than supported by Bi₂O₃ (NaOH). Finally, the quality of the protective shields increased as the energy of the photons of the ionizing rays decreased.
