Preparation of the core-shell HMX@CS microparticles by biological excitation: Excellent hydrophobic-oleophilic properties and decreased impact sensitivity effectively
Inspired by the phenomenon of superhydrophobic plants and animals in nature, 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (HMX)@copper stearate (CS) core-shell composites with similar properties was prepared. A rough shell layer on the surface of the HMX was observed by scanning electron microscopy (SEM),...

| description | Inspired by the phenomenon of superhydrophobic plants and animals in nature, 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (HMX)@copper stearate (CS) core-shell composites with similar properties was prepared. A rough shell layer on the surface of the HMX was observed by scanning electron microscopy (SEM), and a series of in-depth characterization confirmed the successful generation of CS and the core-shell structure of the samples. Differential scanning calorimeter (DSC) proves that the crystal transition temperature (204 °C) and high temperature decomposition exothermal temperature (284 °C) of HMX@CS is almost unchanged compared with pure HMX, which means HMX and CS have good compatibility. Then, the H50 of the samples also increased continuously (16.6 cm→33.7 cm) when the CS shell content increased from 1% to 5%, indicating that the CS shell has a certain buffering performance, and CS will absorb some heat and melt under the stimulation of impact due to its low melting point, which improved impact sensitivity of HMX effectively further. Moreover, HMX@CS has excellent hydrophobic and oleophilic performance, shows excellent wettability with lipid binder, and samples with appropriate CS shell content can continue to combustion stably after covering water. This waterproof and low sensitivity coating provides a new way for the development of multifunctional energetic materials. |
