Core-Shell Graphitic Carbon Nitride/Zinc Phytate as a Novel Efficient Flame Retardant for Fire Safety and Smoke Suppression in Epoxy Resin

Novel core-shell graphitic carbon nitride/zinc phytate (g-C(3)N(4)/PAZn) flame retardant was simple synthetized using two-dimensional g-C(3)N(4) and bio-based PAZn by self-assembly and incorporated into epoxy resin (EP) for improving the fire safety. The flame retardance and smoke suppression were i...

Sumario:Novel core-shell graphitic carbon nitride/zinc phytate (g-C(3)N(4)/PAZn) flame retardant was simple synthetized using two-dimensional g-C(3)N(4) and bio-based PAZn by self-assembly and incorporated into epoxy resin (EP) for improving the fire safety. The flame retardance and smoke suppression were investigated by cone calorimetry. The results indicated that g-C(3)N(4)/PAZn-EP displayed outstanding flame retardancy and smoke suppression, for example, the peak heat release rate and peak smoke production rate decreased by 71.38% and 25%, respectively. Furthermore, the flame retardancy mechanism was further explored by char residue and thermal stability analysis. It can be predicted that g-C(3)N(4)/PAZn will provide valuable reference about bio-based flame retardant.
