To improve the safety of CL‐20, rGO was integrated into CL‐20 (CL‐20/rGO) by in‐situ reduction. The prepared composites were characterized by Scanning electron microscopy, Raman spectroscopy, X‐ray photoelectron spectroscopy, High‐performance liquid chromatography and Power X‐ray diffraction, which proves that the presence/encapsulation of rGO on CL‐20 surface would not change the molecular structure, amount and crystal form of raw CL‐20. In addition, the thermal stability of the composites has improved, while the mechanical sensitivity was desensitized compared to raw CL‐20, suggesting this in‐situ reduction could be utilized to improve the safety of CL‐20.
