Развитие технологии синтеза магнитных наночастиц металлов и сплавов открыло возможность их применения в области радиопоглощающих материалов. В работе представлен обзор результатов исследований свойств нанокомпозитов, приведена методика синтеза металл-углеродных нанокомпозитов пиролизом с использованием инфракрасного нагрева, исследованы зависимости магнитных, электромагнитных и радиопоглощающих свойств полученных нанокомпозитов от температуры синтеза и концентрации металла. Кроме того, проанализированы способы управления радиопоглощающими свойствами гибридных композитов и улучшения согласования электромагнитного импеданса, представлен сравнительный анализ эффективности поглощения электромагнитного излучения нанокомпозитами FeCo/C, синтезированными различными методами. Показано, что выбранные металлы, сплавы (FeCo) и углеродный материал эффективны для изоляции магнитных наночастиц при создании гибридных радиопоглощающих композитов. Управление морфологией и свойствами металл-углеродных нанокомпозитов возможно посредством применения тех или иных подходов к синтезу, варьирования составов прекурсоров и ориентацией наночастиц FeCo, синтезированных в виде чешуек в композите. Полученные результаты могут быть использованы для совершенствования методики применения нанокомпозитов FeCo/C, полученных пиролизом металл-органических прекурсоров на основе полиакрилонитрила, в области радиопоглощающих материалов.

Development of the technology for the synthesis of magnetic nanoparticles of metals and alloys has opened up the possibility of their use in the field of radar-absorbing materials (RAM). The results of studying the properties of nanocomposites, method for the synthesis of metal-carbon nanocomposites by pyrolysis using infrared heating are reviewed. The magnetic, electromagnetic, and radar-absorbing properties of the obtained nanocomposites depending on the synthesis temperature and metal concentration were studied. It is shown that the chosen metals, alloys (FeCo) and carbon material are effective for isolating magnetic nanoparticles when developing hybrid radar-absorbing composites. Moreover, methods for controlling the radar-absorbing properties of hybrid composites and the prospects for improving the impedance matching are considered. An analysis of the efficiency of absorption of electromagnetic radiation by FeCo/C nanocomposites synthesized by different methods is presented. The possibility of controlling the morphology and properties of metal-carbon nanocomposites using certain approaches to synthesis, varying the compositions of precursors, and the orientation of FeCo nanoparticles synthesized in the form of flakes in the composite has been revealed. The results of the study can be used to improve the technique of using FeCo/C nanocomposites obtained by pyrolysis of organometallic precursors based on polyacrylonitrile in the field of radar-absorbing materials.
