One of the major impediments to their use is that Al<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub> shell significantly decreases overall performance. To address this issue, we investigate creating aluminum particles with a glycidyl azide polymer (GAP) coating to improve their reactivity while retaining their energy content. We found that the aluminum particles were coated with a GAP layer of thickness around 8.5\u00a0nm. The coated aluminum particles were compared to non-coated powder by the corresponding reactivity parameters obtained from simultaneous differential scanning calorimetry, thermal gravimetric analysis, coupled with mass spectral and infrared spectral analyses. Besides, the comparison on the energy content was also conducted based on <jats:italic>P<\/jats:italic>\u2013<jats:italic>t<\/jats:italic> tests and a laser-induced air shock from energetic materials (LASEM) technique. It was found that GAP shifted the oxidation onset of aluminum particles to a lower temperature by\u2009~\u200910\u00a0\u00b0C. Besides, the oxidation activation energy of aluminum particles was also reduced by\u2009~\u200915\u00a0kJ\u00a0mol<jats:sup>\u22121<\/jats:sup>. In return, aluminum particles reduced the activation energy of the second stage decomposition of the GAP by 276\u00a0kJ\u00a0mol<jats:sup>\u22121<\/jats:sup>. And due to the synergistic effect between aluminum and GAP, the decomposition products of GAP were prone to be oxycarbide species rather than carbonitride species. In addition, the <jats:italic>P<\/jats:italic>\u2013<jats:italic>t<\/jats:italic> test showed the peak pressure and pressurization rate of GAP coated aluminum particles were separately 1.4 times and 1.9 times as large as those of non-coated aluminum particles. Furthermore, the LASEM experiment suggested the shock wave velocity of the GAP coated aluminum particles was larger than that of non-coated aluminum particles, and the largest velocity difference for them could be 0.6\u00a0km\u00a0s<jats:sup>\u22121<\/jats:sup>. This study suggests after coating by GAP, the aluminum particles possess enhanced reaction performance, which shows potential application value in the fields of aluminized explosives and other energetic fields.<\/jats:p>","DOI":"10.1038\/s41598-022-12949-0","type":"journal-article","created":{"date-parts":[[2022,5,25]],"date-time":"2022-05-25T18:04:08Z","timestamp":1653501848000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Nitrogen-rich energetic polymer powered aluminum particles with enhanced reactivity and energy content"],"prefix":"10.1038","volume":"12","author":[{"given":"Yaru","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Ren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinzhou","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huixin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xilong","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,5,25]]},"reference":[{"issue":"3","key":"12949_CR1","doi-asserted-by":"publisher","first-page":"4417","DOI":"10.1016\/j.proci.2020.08.010","volume":"38","author":"AW Marsh","year":"2021","unstructured":"Marsh, A.
