Influence of nanosized semiconducting additives on the properties of energy-storage phase-change materials subjected to a high-intensity electron beam

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

“…In addition to the high energy flux density, the flammability of the investigated ESC during laser initiation could be affected by light-absorbing additives, which are additives of multilayer graphene. It should be noted that during the electron-beam initiation the particles of graphene (which is a conductor) were not realized as local centers of attraction of electrons, which was discussed in work [22]. As a result of the formation of such local centers, the so-called hot spot mechanism could be realized, which could lead to the excitation of the combustion process [23,24].…”

“…As a result of the formation of such local centers, the so-called hot spot mechanism could be realized, which could lead to the excitation of the combustion process [23,24]. The lack of formation of local centers of attraction is obviously due to the low density of graphene sheets (∼ 2.2 g/cm 3 [25]) compared to the density of additives (copper oxide particles), which were considered in work [22] (ρ = 6.4 g/cm 3 ).…”
