N2 - A novel micro-nano ferric perfluorooctanoate [Fe(PFO) 3 ] was prepared and added in AP/Al/HTPB composite solid propellant as a catalyst to study its effects on burning and thermal decomposition properties of the propellant. To further discuss the possible thermal mechanism of the propellant containing Fe(PFO) 3 , the major effects of Fe(PFO) 3 catalyst on Al were investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and X-ray diffraction (XRD). Results show that By adding 3 w.t.% Fe(PFO) 3 , the burning rate could increase by 27.8 % at 3 MPa, meanwhile, the pressure exponent decreased. The aggregation/agglomeration process of the propellant containing Fe(PFO) 3 efficiently suppressed, and the particle size of condensed combustion products decreased clearly. In addition, Fe(PFO) 3 could reduce the thermal decomposition temperature of the propellant and enhance the heat release. Thermite reaction between decomposition products of Fe(PFO) 3 and Al was triggered at 635 °C, resulting in heat release and formation of α-Al 2 O 3 .
