Article Preview

The HTPB-coated aluminum nanopowders were prepared by using horizontally-mounted kneading machine. The HTPB-coated aluminum nanopowders were characterized by TEM, XRD and FTIR. The exothermic characterization of the HTPB-coated aluminum nanopowders was analysized by simultaneous TG-DSC. The results show that the HTPB-coated aluminum nanopowders have a core-shell structure and the release heat enthalpy in pure oxygen is 4.954KJ/g at 542.7°C. The stability of HTPB-coated aluminum nanopowders excelled Al2O3-passivated aluminum nanopowders due to the hydrophobic nature of HTPB and the hydrophilic nature of Al2O3.
