Abstract: Polymer nanocomposite fire retardancy has turned into a fundamental parameter in modern material application. Late understanding has demonstrated the eco-compliancy of graphene nanoparticles as fire retardants when consolidated into polymer nanocomposites (PNCs). The carbonaceous nanofillers, for example, graphene and graphene oxide assume competent role because of exceptional structural and functional properties having a broad scope of specialized applications. Based on their structural network pattern that determines unique mechanical, electrical and thermal properties. Expanding the amounts of graphene nanoparticles have displayed the capacity to repress basic fundamentally combustibility parameters like Heat release rate (HRR), peak HRR (PHRR), percentage of carbon monoxide generation, smoke production rate and total mass loss rate while at the same time increasing limiting oxygen index, time of ignition moreover, absolute PHRR, in this way hindering combustibility and making better opportunity to reduce loss and causality, all things considered, fire circumstance through the development of even layers of carbonaceous char in the dense stage prepared to do proficiently suppressing the thermal deterioration brought about by oxygen and heat to the polymer network and removing the flaring way. This review strongly emphasize on the flame retardancy mechanism and the effect of combustibility parameters with graphene nanoparticles filled polymer composites.
