A dendritic bonding agent (DBA) that can adhere to CL-20 effectly is reported. The adhesive properties are characterized by scanning electronic microscope (SEM) and X-ray photoelectron spectroscopy (XPS). DBA forms a layer of viscous film on the surface of CL-20; the adhesive degree measured by XPS analysis can be up to 22.87%, the adhesive degree increases by increasing of COOCH₃ group content due to the inducing interaction between N and O.
