Abstract

In the present study, the synthesis of electromagnetic absorber hybrid organic–inorganic mesoporous Al&Fe2O3@NO2–Ph–PMO nanocomposite as a new class of nanoenergetic materials with large density of NO2 groups is investigated. For this purpose, the Al&Fe2O3@NO2–Ph–PMO nanocomposite is prepared in five steps: (1) preparation of hybrid organic–inorganic mesoporous Ph–PMO via sol–gel method, (2) incorporation of NO2 moieties on the surface of Ph–PMO by nitration reaction, (3) preparation of iron oxide magnetite nanoparticles (Fe3O4-MNPs) via a chemical precipitation method and thermotransfer to hematite (Fe2O3-MNPs), (4) development of the nanocomposite embedded Fe2O3-MNPs on the surface of hybrid organic–inorganic NO2–Ph–PMO mesoporous structure by ultrasonic method and finally, (5) the preparation and incorporation of Al nanoparticles (as a fuel in thermite reaction) on the surface of Fe2O3@NO2–Ph–PMO using the ultrasound-assisted method which leads to a high energetic nanocomposite propellant, Al&Fe2O3@NO2–Ph–PMO, based superthermite concept. All, the higher loading of the NO2 group on the vast specific surface area of PMO, the electromagnetic absorption property and superthermite character of the nanocomposite are improved and reported in this paper. Finally, the texture and structure of the prepared energetic metastable intermolecular nanocomposite are characterized by FT-IR, XRD, TEM, VSM and N2 sorption analysis.
