چکیده
It remains a challenge to prepare flame-retardant composites via the addition of low content flame retardant. In this work, novel DOPO-functionalized reduced graphene oxide hybrid (DOPO-M-rGO) system was synthesized for epoxy resin (EP). The phosphorus-nitrogen-reduced ternary synergistic effect provided DOPO-M-rGO with high flame-resistance efficiency in EP; thus, EP-based composite exhibited superior fire-resistant performance at extremely loading. limiting oxygen index (LOI) increased from 25% 32% only 1.5 wt% addition, and peak heat release rate (pHRR), total (THR), smoke production (TSP) were significantly decreased by 55%, 30%, 20%, respectively. as halogen-free system, presents great application potential an eco-friendly additive improvement thermosetting polymer materials.

Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...
