The objective of this paper is to make the field of flame retardancy of polymeric materials more accessible. Polymer nanocomposites which are synthesized by carbon nanotubes and metallic oxide nanoparticles are highly recommended in literature. Based on the observations for polymer nanocomposites, it is quite clear that the nanoadditives can exert a definite flame retardant effect, appearing in the form of an increase in the time of ignition and a reduction in the peak heat release rate in cone calorimeter test and burning processes are reduced. Nowadays, as a method of fire protection for civil structures, chemical plants and other facilities, intumescent flame retardant coatings have had an increasing usage and their mechanism can be improved by synergistic agents, i.e. nanoparticles. Production of an effective char residue is critical in achieving a significant enhancement of the thermal and fire performance of the matrix.
