Effect of Nano-copper-Ultrafine Carbon Composite on Thermal Decomposition of CL-20

Ultrathin carbon loaded With nano-copper (Cu-C composite) was mixed With Hexanitrohexaazazo wurtane (CL-20); Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to observe the dispersion of nano-copper in ultra-thin carbon and the composite on the surface of CL-20. The elemental content was analyzed by energy spectrum, and the effect of Cu-C composite on the thermal decomposition of CL-20 at different mixing ratios was analyzed by differential scanning calorimetry (DSC). The results show that the nano-copper is uniformly loaded on the ultrafine carbon and dispersed on the surface of CL-20. DSC results showed that the decomposition peak temperature of CL-20 decreased from 250.6 to 240.5 °C and the activation energy decreased from 222.4 from to 212.4 kJ/mol, indicating that the Cu-C composite had a certain catalytic effect on the thermal decomposition of CL-20.
