Abstract—We study the formation mechanism of carbon nanoparticles with simultaneous formation of a polystyrene film in a AC barrier corona discharge at atmospheric pressure. The importance of the research stems from the need to control the allotropic form of carbon nanoparticles, which affects the physical and technical characteristics of polymer films obtained by this method. It is shown that nucleation of polycrystalline onion-like carbon nanoparticle agglomerates is the basis for graphene flake formation in the corona sheath. Graphene flakes form from these nucleation sites in gas discharge streamers owing to the destruction of monomer molecules remaining in the agglomerates of nucleation sites. It was revealed that the allotropic form of such particles is determined not only by the energy—in this case the barrier corona discharge—but also by the ratio of the duration of its exposure to the characteristic destruction and formation times of covalent bonds participating in the particle process.

测定在等离子体化学反应器中形成聚合物膜时形成的碳颗粒的结构

摘要—我们研究了在大气压力下在交流势垒电晕放电中同时形成聚苯乙烯薄膜的碳纳米粒子的形成机理。该研究的重要性源于控制碳纳米颗粒的同素异形形式的需要，这影响了通过这种方法获得的聚合物薄膜的物理和技术特性。结果表明，多晶洋葱状碳成核纳米颗粒附聚物是在电晕鞘中形成石墨烯薄片的基础。由于残留在成核位置的团聚体中的单体分子的破坏，石墨烯薄片从气体排出拖缆中的这些成核位置形成。结果表明，这种颗粒的同素异形形式不仅取决于能量（在这种情况下为电晕放电的势垒），还取决于其暴露时间与特征性破坏的比例以及参与该过程的共价键形成时间的比值。粒子过程。
