“…The advantage of this composition over traditional primary Ems is the absence of heavy and toxic metals in the composition. Previously, similar pyrotechnic compositions showed pretty high sensitivity to various electrophysical pulses (such as a high-current electron beam of nanosecond duration, a high-voltage discharge, and an electrical explosion of a semiconductor bridge) [29] and thermal effects [30]. However, their susceptibility to coherent radiation remained unexplored.…”

The paper presents the results of a study on the effectiveness of few-layer graphene synthesized under SHS conditions from lignin as a modifying additive in creating composite pyrotechnic complexes based on porous silicon and calcium perchlorate. It was found that the addition of few-layer graphene (20–30 wt. %) could significantly increase the probability of the ignition of pyrotechnic compositions by laser diode (infrared) radiation (wavelength of 976 nm and power of 15 MW/m2) compared to the initial pyrotechnic compositions. Using few-layer graphene also leads to a sharp increase in sensitivity to infrared laser radiation and the initiation of explosive transformations in retrofitted pyrotechnic compositions compared to the initial pyrotechnic compositions. Due to the high productivity and low cost of the technique for synthesizing few-layer graphene, the use of composite pyrotechnic compositions modified with few-layer graphene is profitable in the actual industry. A phenomenological model of the formation mechanism of 2D graphene structures under the conditions of the SHS process is proposed.

Carbonization of a biopolymer (lignin) in self-propagating high-temperature synthesis (SHS) led to the production of 2D graphene structures. With the help of modern analytical methods (Raman spectroscopy, X-ray diffraction) and electron microscopy, the resulting product was confirmed to have a few-layer 2D graphene structure. The predicted photovoltaic properties of the resulting few-layer graphene were implemented for laser ignition of a model pyrotechnic composition based on porous silicon. A phenomenological model of the formation mechanism of 2D graphene structures under the conditions of the SHS process is proposed.

“…The initiation of both conventional energy-saturated materials and porous silicon-based ESCs using a high-current electron beam [3] has the same advantages as the optical method, except that a powerful electric energy source is required, which dramatically increases the size of such an initiation system. These disadvantages can be eliminated by the development of pulsed high-voltage technology.…”

Optical and electron-beam initiation of porous silicon films with different contents of oxidizer and graphene

Laser and electron-beam initiation of the combustion process of energy-saturated composite films were studied. Composites were produced from porous silicon, a fluorine-containing polymer, and graphene. It is shown that the impact of a high-current electron beam of nanosecond duration does not lead to the excitation of the combustion process. Moreover, the process of film combustion during laser initiation is accompanied in some cases by the appearance of a zone of secondary flame and white smoke. Keywords: porous silicon, energy-saturated composite, laser initiation, electron-beam initiation, combustion.
