碳纳米管对高氯酸铵燃烧和热分解的催化作用

Catalytic Action on Combustion and Thermal Decomposition of AP with CNTs

通过干混法、水混法和丙酮混法制备了高氯酸铵(AP)与碳纳米管(CNT s)的复合物,研究了CNT s对AP燃烧和热分解的催化作用。结果表明:随着CNT s添加量的增加,AP/CNT s复合物的燃速增大,压力指数降低;对于相同CNT s添加量的AP/CNT s复合物,CNT s对AP的催化作用依赖于不同的混合方法,按干混法、水混法和丙酮混法的次序,催化作用依次增强,AP/CNT s复合物的燃速依次增大,压力指数依次降低。

Ammonium perchlorate （AP） and carbon nanotubes （CNTs） compound was prepared by different mixing methods, namely dry-mixing method （1）, water mixing method （2） and acetone-mixing method （3）, respectively. Combustion and thermal decomposition of AP with CNTs were studied. The results show that the burning rate of AP/CNTs compound increases, and pressure exponents decrease with the increasing of CNTs. The catalysis of CNTs on AP depend on different mixing methods. For AP/CNTs compounds Ⅰ-Ⅲ prepared by methods 1 - 3 respectively, the catalytic effect enhances, the burning rate increases and the pressure exponent decreases in the order Ⅲ〉 Ⅱ〉 Ⅰ .
