Abstract
In recent years, research in the field of carbon nanomaterials (CNMs), such as fullerenes, expanded graphite (EG), carbon nanotubes (CNTs), graphene, and graphene oxide (GO), has been widely used in energy storage, electronics, catalysts, and biomaterials, as well as medical applications. Regarding energy storage, one of the most important research directions is the development of CNMs as carriers of energetic components by coating or encapsulation, thus forming safer advanced nanostructures with better performances. Moreover, some CNMs can also be functionalized to become energetic additives. This review article covers updated preparation methods for the aforementioned CNMs, with a more specific orientation towards the use of these nanomaterials in energetic compositions. The effects of these functionalized CNMs on thermal decomposition, ignition, combustion and the reactivity properties of energetic compositions are significant and are discussed in detail. It has been shown that the use of functionalized CNMs in energetic compositions greatly improves their combustion performances, thermal stability and sensitivity. In particular, functionalized fullerenes, CNTs and GO are the most appropriate candidate components in nanothermites, solid propellants and gas generators, due to their superior catalytic properties as well as facile preparation methods.
Highlights
Energetic materials (EMs) are a class of materials with a large amount of stored chemical energy, which can be rapidly released; typical subclasses of EMs include explosives, pyrotechnics and propellants
Many other papers reporting carbon nanotubes (CNTs), expanded graphite (EG) and carbon black (CB) materials and their applications in the field of EMs have still not been reviewed and summarized. To make such a large amount of data on carbon nanomaterials (CNMs), especially that published in Chinese journals, available to all readers, this review aims to summarize preparation methods of CNM-based EMs as well as their effects on the performance and sensitivity of the corresponding energetic compositions
EG had only been used in chemical heat pumps, it may have additional uses in the field of EMs, e.g., as an additive in nanothermites and as a promising flame retardant additive in cladding materials for solid propellant charges
