Abstract

Phosphorus incorporation into carbon can greatly modify its chemical, electronic and thermal stability properties. Up to today, this has been limited to low levels of phosphorus. Herein we report a simple, large?scale synthesis of carbon?nitrogen?phosphorus (CNP) materials with tunable elemental composition, leading to excellent thermal stability to oxidation and fire?retardant properties. The new synthesis consists in using monomers that are liquid at high temperatures as the reaction precursors. The molten?state stage leads to good monomers miscibility and enhanced reactivity at high temperatures and to the formation of CNP materials with up to 32% phosphorus incorporation. The CNP composition and fire?retardant properties can be easily tuned by modifying the starting monomers ratio and the final calcination temperature. The CNP materials demonstrate great resistance to oxidation and excellent fire?retardant properties, with up to 90 % of the materials preserved upon heating to 800 °C in air.
