Effect of Graphene Additions on the NCP Initiation Threshold in Spectrum-Selective Excitation

详细

The effect of graphene additions on the initiation threshold of (5-nitrotetrazolato-N²)pentamminecobalt(III) perchlorate in excitation in the overtone of the vibration mode (λ = 1554 nm) was studied. The dependence of the initiation threshold power on the graphene content passes through a minimum at 3 wt % graphene. In this case, the threshold power decreases by a factor of ∼10. The minimum obtained value of the threshold power density is 0.15 W mm⁻². The dependence of the initiation threshold power on the content of the absorbing impurity was considered theoretically. Based on the data obtained, the use of erbium lasers, including fiber lasers operating at a wavelength of 1.55 μm, for initiation of energetic complexes based on cobalt aminates was suggested.
