摘要:采用溶胶-凝胶与溶剂-非溶剂相结合的方法制备Fe2O3/AP复合含能材料，探究最优的合成条件，并对Fe2O3/AP复合含能材料的组成、形貌及热分解性能进行表征分析。研究表明：在H2O用量为10mL，PO用量为wPO∶wFe3+=20，反应温度为45℃的最优合成条件下，制备的Fe2O3溶胶粒子为纳米级别且在AP中分散均匀；与纳米Fe2O3和AP的物理共混样品相比，Fe2O3/AP复合含能材料的高温放热峰温提前了13.6℃，表观分解热增加了170.2J/g，说明Fe2O3/AP复合粒子中纳米氧化铁表现出更高的催化效率。
Abstract:The Fe2O3/AP composite energetic materials were prepared by combining method of sol-gel and solvent-nonsolvent ,and the optimal process conditions were explored. The composition, morphology and thermal decomposition property of the obtained composite particles have been characterized and analyzed. The study show that the final optimized preparation conditions are H2O in an amount of 10mL, PO in an amount of 20 times as much as that of Fe3+ and reaction temperature of 45oC. The prepared Fe2O3 particles are nanoscale and disperse evenly in the AP particles. Compared with the simply mixed sample of nanometer sized Fe2O3 particles and AP, the peak temperature of high temperature decomposition of Fe2O3/AP composites is decreased by 13.6oC, and the total heat release is increased by 170.2J/g. The results show that nanometer-sized Fe2O3 particles of Fe2O3/AP composites show higher catalytic performance for the thermal decomposition of AP.
