摘要
采用新新型电泳组装法成功制备含能纳米铝热剂Al/(Fe2O3)Ⅲ,采用扫描电镜等技术对铝热剂薄膜的微观形貌进行了分析。并通过对比差示扫描量热法等对铝热剂放热性能进行探究。结果表明:场强为20V/mm下,选用聚乙烯亚胺和聚乙烯胺为混合改性剂可以成功实现样品的电泳组装,并且含能薄膜相对均匀,无大量聚团出现。体系的Zeta电位约为70,说明悬浮体系稳定性高。此外,纳米Al/Fe2O3铝热剂薄膜放热量达到4.32MJ/kg,说明产品具有极强的热量输出能力。
The nano-Al/(Fe2O3)Ⅲ energetic materials have been fabricated by electrophoretic assembly method.The microstructures and exothermic properties of product were analyzed by field emission scanning electron microscopy and differential scanning calorimeter.The results show that the electrophoretic assembly of product is realized by using polyethyleneimine and polyvinylamine as mixed modifiers when the field strength is 20 V/mm,and the energetic film is relatively uniform with a large number of agglomerates on that surface.The zeta potential of this optimal system is ca.70,indicating that the suspension system has high stability.In addition,the heat release of the product reaches 4.32 MJ/kg,indicating a strong heat output capability.
