Abstract Composite microcrystals of the cyclic nitramines 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (ε-CL-20), 1,3,5-trinitro-1,3,5-triazinane(RDX), 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (β-HMX), and cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX) with polyaniline (PANi) have been prepared thoroughly characterized in terms morphology phase purity. PANi outperformed other conducting polymers selectivity towards NAs due to its better interaction NAs, low production cost, ease preparation. The bonding polymeric chain has examined by means Fourier transform infrared (FTIR), Raman spectroscopy methods, fluorescence quenching; spectrum shown laser sensitivity these microcrystals. Powder X-ray diffraction results changes polymorph modifications CL20 (from ɛ β) HMX β α) during preparation composites, which also confirmed spectral differential thermal analysis techniques. structural orientations found composites significantly stabilize against impact; their detonation properties slightly deteriorated, but electrical conductivity strongly increased electric-spark sensitivity. above determine potential use mainly as parts electric or impulse initiators, having “a green character”, for various charges.
