“…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 fairly high sensitivity to various electrophysical pulses (such as a high-current electron beam of nanosecond duration, a high-voltage discharge, an electrical explosion of a semiconductor bridge) [41,42], and thermal effects [43]. However, their susceptibility to coherent radiation remained unexplored.…”

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.
