The objective of this work is to try to create new behaviors of energetic materials by using sol-gel processing and freeze drying to incorporate the energetic material into the fuel matrix at the nano particle size scale. Hydrazinium diperchlorate ([N2H6][ClO4](2)) and resorcinol-formaldehyde were chosen in one example, and CL-20 and nitrocellulose were chosen in another. High solids loadings were achieved by the cryogel method. Characterization was carried out by elemental analysis, SEM, TEM, AFM, T-jump/FTIR spectroscopy, DSC, and drop-weight impact testing. The nanoscale formulations do indeed exhibit several different behaviors, such as enhanced burning characteristics and unusual morphologies, and appear to be a promising direction to pursue.
