Special Issue Information

Dear Colleagues,

Micro/nano energetic materials are ultrafine and usually have an average particle size of up to 20 micrometers (they can be as small as a few nanometers). Micro/nano energetic materials have higher combustion and energy release efficiencies and complete combustion and explosion processes due to their small particle size, large specific surface area, high surface energy, and surface activity. In the formulation of energetic materials, the micro/nanometer particle size gradation is often used to regulate the charge density and energy release of weapons charges to improve their mechanical properties and safety performance. Micro and nano technologies have become the key technology and research hotspot for the revolutionary change in energetic materials. This Special Issue provides a platform for researchers to exchange advanced technologies and performance of micro/nano energetic materials. The research areas include but are not limited to the following areas: emerging technologies and methods for the preparation of micro/nano energetic materials, characterization technologies for micro/nano energetic materials, numerical simulation of the performance for micro/nano energetic materials, application performance of micro/nano energetic materials, and energy release mechanism of micro/nano energetic materials.

Strengthening the interfacial contact between the reactive components effectively boosts the energy release of energetic materials. In this study, we aimed to create a close-knit interfacial contact condition between aluminum nanoparticles (Al NPs) and Polyvinylidene fluoride-hexafluoropropylene (P(VDF-HFP)) through hydrolytic adsorption and assembling 1H, 1H, 2H, 2H-Perfluorododecyltrichlorosilane (FTCS) on the surface of Al NPs. Leveraging hydrogen bonding between –CF and –CH and the interaction between C–F⋯F–C groups, the adsorbed FTCS directly leads to the growth of the P(VDF-HFP) coating layer around the treated Al NPs, yielding Al@FTCS/P(VDF-HFP) energetic composites. In comparison with the ultrasonically processed Al/P(VDF-HFP) mixture, thermal analysis reveals that Al@FTCS/P(VDF-HFP) exhibits a 57 °C lower reaction onset temperature and a 1646 J/g increase in heat release. Associated combustion tests demonstrate a 52% shorter ignition delay, 62% shorter combustion time, and a 288% faster pressurization rate. These improvements in energetic characteristics stem from the reactivity activation of FTCS towards Al NPs by the etching effect to the surface Al2O3. Moreover, enhanced interfacial contact facilitated by the FTCS-directed growth of P(VDF-HFP) around Al NPs further accelerates the whole reaction process. Full article
