“…CuO at the nanoscale still showed a good catalysis performance in the propellant due to the strong heat and mass transfer capabilities of nano-CuO nanoparticles or clusters. For pure DAP-4, the high thermal stability is from the cage-like framework of perovskite structure [17,[31][32][33]. Therefore, more energy needs to be provided to destroy the cage-like framework structure at a higher heat-induced decomposition temperature.…”

In this study, the effect of copper oxide (CuO) with different sizes on the heat-induced catalysis decomposition of typical molecular perovskite-based energetic material DAP-4 was studied. Pure CuO with different sizes and DAP-4 are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Heat-induced catalysis decomposition performances of DAP-4 with adding CuO were investigated by differential scanning calorimeter (DSC). Results demonstrated that with a lower-addition CuO at the nanoscale added (1 wt%), DAP-4 had decreased at least by 36°C with the heating rate of 10°C/min, compared with pure DAP-4. With the CuO particle size of 50 nm, the E a of DAP-4 heat-induced decomposition in DAP-4/CuO-50 had reduced from 159.8 kJ/mol to 120.2 kJ/mol, which is lower than DAP-4/CuO-150. The heat-induced catalysis decomposition mechanism of DAP-4 by using CuO as a nanoadditive was proposed.

“…[ 20 ] Especially, (H 2 DABCO)[NH 4 (ClO 4 ) 3 ] is given remarkable attention. [ 21 ] In addition, four silver‐based PEMs may have the potential to be primary explosive candidates because of their excellent calculated detonation performances and high sensitivities. [ 22 ] Although the reported perchlorate‐based PEMs have shown considerable calculated detonation velocity, the energy of them still needs to be experimentally verified while their initiation ability is still unknown.…”

The requirements for high energy and green primary explosives are more and more stringent because of the rising demand in the application of micro initiation explosive devices. Four new energetic compounds with powerful initiation ability are reported and their performances are experimentally proven as designed, including non‐perovskites ([H2DABCO](H4IO6)2·2H2O, named TDPI‐0) and perovskitoid energetic materials (PEMs) ([H2DABCO][M(IO4)3]; DABCO=1,4‐Diazabicyclo[2.2.2]octane, M=Na+, K+, and NH4+ for TDPI‐1, ‐2, and ‐4, respectively). The tolerance factor is first introduced to guide the design of perovskitoid energetic materials (PEMs). In conjunction with [H2DABCO](ClO4)2·H2O (DAP‐0) and [H2DABCO][M(ClO4)3] (M=Na+, K+, and NH4+ for DAP‐1, ‐2, and ‐4), the physiochemical properties of the two series are investigated between PEMs and non‐perovskites (TDPI‐0 and DAP‐0). The experimental results show that PEMs have great advantages in improving the thermal stability, detonation performance, initiation capability, and regulating sensitivity. The influence of X‐site replacement is illustrated by hard–soft‐acid–base (HSAB) theory. Especially, TDPIs possess much stronger initiation capability than DAPs, which indicates that periodate salts are in favor of deflagration‐to‐detonation transition. Therefore, PEMs provide a simple and feasible method for designing advanced high energy materials with adjustable properties.

“…However, the possible structural designs that can be achieved with just these four elements of CHNO have nearly been exhausted; additionally, the density and detonation performance of CHNO energetic materials have gradually reached the bottleneck, and sensitivity cannot be guaranteed while enhancing energetic performance [21–25] . Considering the electronic structural design of explosives, synthetic routes, and detonation decomposition mechanisms, the introduction of fluorine, sulfur, boron, and bromine to energetic materials is the latest trend in the fields of explosives and propellants [26–31] . Among the above elements, fluorine is most widely studied because it is the most electronegative non‐metallic element and has a high density as well as calorific value [32,33] …”

Molecules featuring fluorine‐containing functional groups exhibit outstanding properties with high density, low sensitivity, excellent thermal stability, and good energetic performance due to the strong electron‐withdrawing ability and high density of fluorine. Hence, they play a pivotal role in the field of energetic materials. In light of current theoretical and experimental reports, this review systematically focuses on three types of energetic materials possessing fluorine‐containing functional groups F‐ and NF2‐ substituted trinitromethyl groups (C(NO2)2F, C(NO2)2NF2), trifluoromethyl group (CF3), and difluoroamino and pentafluorosulfone groups (NF2, SF5) and investigates the synthetic methods, physicochemical parameters, and energetic properties of each. The incorporation of fluorine‐containing functional moieties is critical for the development of novel high energy density materials, and is rapidly being adopted in the design of energetic materials.
