To improve the dispersion of Fe2O3 nanoparticles in solid propellant, the Fe2O3/hydroxyl-terminated polybutadiene (HTPB) composite nanoparticles were prepared by one-step blending (OSB) method and two-step blending (TSB) method, respectively. The HRTEM, TGA, FTIR and XRD were used to characterize the structure of the resultant composite nanoparticles. It was observed that HTPB could be physically coated on the surface of the Fe2O3 nanoparticles with both the two methods. Whereas the composite nanoparticles prepared by TSB method had better structure, in which the Fe2O3 nanoparticles exhibited better dispersion and the depth of the HTPB was uniform. After the composite process for the hydrophilic Fe2O3, the composite nanoparticles showed hydrophobicity. As a result, it can be deduced that the Fe2O3 nanoparticles in Fe2O3/HTPB composite nanoparticles had better dispersion in solid propellant.
