“…The mostly reported intumescent flame retardants (IFRs) are the phosphorus-nitrogen containing compounds, which are considered as the promising candidate for replacing halogen containing ones due to their high efficiency and have not been proved to create environmental problems so far. However, these intumescent additives are somewhat volatile and susceptible to migration to the surface during the high temperature processing due to their low molecular weight, and consequently decreases the flame retardancy efficiency [2,3]. To synthesize high molecular weight, namely oligomeric or polymeric IFRs, provides a good strategy to solve the above problems, and previous work in our laboratory showed that this strategy was very successful [4].…”

The present chapter deals with a brief account on various types topics in flame retardant of polymer nanocomposites. This chapter discussed with different topics such as flame retardancy of polymer nanocomposite, recent developments in different techniques used for the flame retardancy, recent development of phosphorus flame retardants in thermoplastic blends and nanocomposites, non-halogen flame retardants in epoxy-based composites and nanocomposites, flame retardant/ resistant based nanocomposites in textile, flame retardants in bitumens and nanocomposites, fire retardant for phase change material, flame retardant finishing for textiles, flame retardant of cellulosic materials and their composites. Flame Retardancy of Polymer NanocompositeFrom the application view polymers are very flammable materials, for preventing this flammability, scientists need to improve polymer fire retardancies, and this is a major challenging. Developing the effective environmentally friendly flame retardants is challenging. Because of this materials are very hazardous; they are widely used owing to their effectiveness and low cost. Flame retardant nanocomposites with conventional fire retardants to develop more-efficient materials showing improved mechanical properties. There are numerous nanofiller/conventionalfire-retardant already prepared. From some of the work related to CNTs shows that improve the flammable properties of nanocomposites also improved the mechanical properties such as electrical, thermal properties. Nanofiller-based flame retardants show high flame-retardant efficiencies. Nanofiller can reduce the peak heat release rates (PHRRs) of polymers and thus reduce the speed at which

“…7 Toldy et al synthesized efficient organophosphorous compounds and used them in epoxy resins. 8 The results exhibited that the limiting oxygen index (LOI) value is increased from 21 to 28 by addition of the organophosphorous compounds. Liu et al synthesized a nonflammable phosphazene-based epoxy resin and studied the thermal and flame retardancy of the epoxy resin cured with four curing agents.…”

In this study, a novel phosphorus-containing flame retardant copolymer of spirocyclic pentaerythritol di(phosphate monochloride) and bisphenol S (SPD-BS) was successfully synthesized and used as a flame retardant in diglycidyl ether of bisphenol A (DGEBA) epoxy resins. The chemical structure of the SPD-BS was characterized using FT-IR and 1 H NMR spectra. The thermal properties were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The effects of SPD-BS and nano-CaCO3 on the flame-retardant properties of DGEBA/SPD-BS systems were evaluated by measurement of the burning rate. As a result, the thermal stabilities of the DGEBA/SPD-BS systems were decreased with increasing SPD-BS content. The flame-retardant properties and char yields of the systems were significantly increased when SPD-BS content increased. The synergism of nano-CaCO3 incorporation on flame retardancy was found for the DGEBA/SPD-BS systems.
