“…In addition to high sensitivity, there are other factors limiting the use of nanothermites [ 14 ], including stability problems, for example, oxidation [ 59 ] or coalescence [ 60 , 61 , 62 ] during storage; the difficulty of obtaining a homogeneous composite mixture [ 55 , 63 ]; gradual increase in the viscosity of compositions with a binder [ 64 ]. Furthermore, toxicological hazard remains an important issue when handling nanopowders [ 52 , 53 ].…”

“…The main role of the binder is to improve the mechanical properties of the composite [ 65 ]. The binder encapsulates the powder particles, reducing their oxidation and coalescence [ 62 ]. Another possible role for the polymeric binder lies in increasing the energy of the composition if the binder reacts with the filler particles.…”

This article dwells upon the additive manufacturing of high-energy materials (HEM) with regards to the problems of this technology’s development. This work is aimed at identifying and describing the main problems currently arising in the use of AM for nanostructured high-energy materials and gives an idea of the valuable opportunities that it provides in the hope of promoting further development in this area. Original approaches are proposed for solving one of the main problems in the production of nanostructured HEM—safety and viscosity reduction of the polymer-nanopowder system. Studies have shown an almost complete degree of deagglomeration of microencapsulated aluminum powders. Such powders have the potential to create new systems for safe 3D printing using high-energy materials.

Highly Reactive Thermite Energetic Materials: Preparation, Characterization, and Applications: A Review

et al. 2023

View full text Add to dashboard Cite

As a promising kind of functional material, highly reactive thermite energetic materials (tEMs) with outstanding reactive activation can release heat quickly at a high reaction rate after low-energy stimulation, which is widely used in sensors, triggers, mining, propellants, demolition, ordnance or weapons, and space technology. Thus, this review aims to provide a holistic view of the recent progress in the development of multifunctional highly reactive tEMs with controllable micro/nano-structures for various engineering applications via different fabricated techniques, including the mechanical mixing method, vapor deposition method, assembly method, sol-gel method, electrospinning method, and so on. The systematic classification of novel structured tEMs in terms of nano-structural superiority and exothermic performance are clarified, based on which, suggestions regarding possible future research directions are proposed. Their potential applications within these rapidly expanding areas are further highlighted. Notably, the prospects or challenges of current works, as well as possible innovative research ideas, are discussed in detail, providing further valuable guidelines for future study.

“…Owing to the high energy density, thermites have drawn considerable attentions in energetic materials . However, conventional thermites are constituted of micro‐sized fuels and oxidizers, which brings about low mass transfer rate, poor homogeneity and less contact area, resulting in slow reaction rate and high ignition temperature, thus restricting their applications in solid propellants. Nevertheless, these phenomena do not occur in nano‐sized thermites.…”

Thermites are widely employed in explosives and propellants. However, it is difficult to fabricate nanothermites with low cost, nanoscale size and large production simultaneously. In this work, we employed ball milling process to manufacture varying ratio of FeF3‐containing nanothermites in a large scale. The obtained nanothermites presented excellent stability and were characterized by X‐ray diffraction, nitrogen adsorption‐desorption isotherms and scanning electron microscopy. The nanothermites particles could be optimized into nearly spherical shape together with an average diameter of 23.2 nm and a specific surface area of 26.33 m2/g. Moreover, the thermal stabilities, hydrophobicities and combustion properties were also symmetrically investigated via thermogravimetric analysis, hydrophobic angle test and infrared temperature measurement, showing that the vinyltrimethoxysilane covered FeF3‐containing nanothermites displayed similar hydrophobicity, lower initial oxidation temperatureand faster burning rate, respectively, compared to the ball‐milled aluminum nanoparticles.
