Significance of Carbon Nanotube in Flame-Retardant Polymer/CNT Composite: A Review

In this review, flame-retardant characteristics of polymer/carbon nanotube composite have been focused. Nonflammability behavior of carbon nanotube filler with different types of polymer matrices has been discussed. In addition, thermal, mechanical, and electrical properties of these materials have also been argued. Main types of polymers considered are epoxy, polystyrene, polyaniline, polypropylene, and polyurethane. Considerable enhancement in nonflammability properties of polymers with carbon nanotube was studied using limiting oxygen index measurement, UL 94 tests, and cone calorimetry. Toward the end, significance of flame-retardant composites in aerospace, electronics, radar absorbing materials, electromagnetic shielding, and wind turbine blades has been conversed.
