High-efficiency phosphorus/nitrogen-containing flame retardant on epoxy resin

•A novel phosphorus/nitrogen-containing hybrid containing phosphophenanthrene and nitrile groups•It significantly improved both thermal stability and flame retardancy of epoxy resins at low phosphorus content.•The flame-retardant mechanism acted in both gas phase and condensed phase.•Limiting oxygen...
