摘      要：Improving the thermal decomposition performance of hexanitrohexaazaisowurtzitane(CL-20)by appropriate methods is helpful to promote the combustion performance of CL-20-based solid *** this study,we synthesized a sandwich structure of CL-20 and nanoporous carbon scaffolds film(NCS)and emphatically studied the thermal decomposition performance of the composite *** analysis and differential scanning calorimetry were used to measure the thermal decomposition process of the composite *** kinetic parameters of thermal decomposition were calculated by the thermal dynamic analysis software *** results showed that the thermal decomposition performance of the sandwich structure of CL-20 and NCS was better than *** the tested samples,NCS with a pore size of 15 nm had the best catalytic activity for the thermal decomposition of ***,the thermal decomposition curve of the composite structure at the heating rate of 1 K/min was deconvoluted by mathematical method to study the thermal decomposition *** a possible catalytic mechanism was *** excellent thermal decomposition performance is due to the sandwich structure enhances the interface reaction of CL-20 and *** work may promote the extensive use of CL-20 in the field of solid rocket propellant.
