Chapter 7: Green Synthesis of Organic–Inorganic Hybrid Fire Retardants^†

This chapter presents the developments and the green synthesis of organic–inorganic hybrid fire retardants such as the self-assembly of polyelectrolytes and nanoparticles from aqueous media, the functionalization of ammonium polyphosphate (APP) by various modification methods, and the flame retardant modification of metal–organic frameworks (MOFs) and the rare-earth/transition metal complex flame retardants. They are systematically expounded from their composition to their preparation as well as their applications. For each substrate, the best performing solutions are presented for analysing the main flame retardant mechanism while also providing a general comparison in terms of properties vs. processing efficiency.
