Morphology controlled synthesis of nanoparticles of powerful high energetic compounds(HECs) such as l,3,5-trinitro-l,3,5-triazinane(RDX) and 1,3,5,7-tetranitro-l,3,5,7-tetrazocane(HMX) were achieved by a simple solvent—antisolvent interaction(SAI) method at 70 ℃.The effects of different solvents on particle size and morphology of the prepared nano-HECs were studied systematically.Particle size and morphology of the nano-HECs was characterized using field emission scanning electron microscopy(FE-SEM) imaging.X-ray diffraction(XRD) and Fourier transform infrared(FTIR) spectroscopy studies revealed that RDX and HMX were precipitated in their most stable polymorphic forms,i.e.a and P,respectively.Thermogravimetric analysis coupled with differential scanning calorimetry(TGA-DSC) studies showed that the thermal response of the nanoparticles was similar to the respective raw-HECs.HEC nanoparticles with spherical and rod shaped morphology were observed under different solvent conditions.The mean particle size also varied considerably with the use of different solvents.
Morphology controlled synthesis of nanoparticles of powerful high energetic compounds (HECs) such as l, 3,5-trinitro-l, 3,5-triazinane (RDX) and 1,3,5,7-tetranitro-l, 7-tetrazocane (HMX) were achieved by a simple solvent-antisolvent interaction (SAI) method at 70 ° C. The effects of different solvents on particle size and morphology of the prepared nano-HECs were studied systematically. Particle size and morphology of the nano -HECs was characterized using field emission scanning electron microscopy (FE-SEM) imaging. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy studies studies that RDX and HMX were precipitated in their most stable polymorphic forms, iea and P , respectively.Thermogravimetric analysis coupled with differential scanning calorimetry (TGA-DSC) studies showed that the thermal response of the nanoparticles was similar to the respective raw-HECs. He nanoparticles with spherical and rod-shaped morphology were observed under different solvent conditions.Th e mean particle size also varied considerably with the use of different solvents.
