Preparation and Exothermic Characterization of Dioctyl Sebacate (DOS)-Coated Aluminum Nanopowders
The DOS-coated aluminum nanopowders were prepared by using a kneader. The DOS-coated aluminum nanopowders were characterized by TEM, XRD and FTIR. The exothermic characterization of the DOS-coated aluminum nanopowders was analysized by simultaneous TG-DSC. The results show that the DOS-coated aluminum nanopowders have a core-shell structure and the release heat enthalpy in pure oxygen is 4.955KJ/g at 529.2°C. The stability of DOS-coated aluminum nanopowders excels Al2O3-passivated aluminum nanopowders due to the hydrophobic nature of DOS and the hydrophilic nature of Al2O3.
