“…At the same time, the Fe 3 O 4 /SWCNT/PDPAC nanomaterials prepared in the interfacial process in an alkaline medium by one-pot method form high stability magnetic uids in ethanol. 50 The analysis of the literature data showed that polymermetal-carbon composites have a high potential for practical use in industry, medicine, energy and human life due to their multifunctionality. However, their practical application is hindered by the complexity of the multi-stage synthesis of such ternary nanomaterials.…”

“…One of the most common ways to prevent the aggregation of magnetic nanoparticles is to immobilize them on the surface of a carbon material or to stabilize them in a polymer matrix. In recent years, particular interest has been shown in ternary hybrid multifunctional nanocomposites, which include conjugated polymers, magnetite nanoparticles, and carbon nanomaterials [19][20][21][22][23]. Of the carbon nanomaterials of interest are carbon nanotubes, which are hollow cylindrical structures with diameters ranging from a tenth of a nanometer to several tens of nanometers.…”

A hybrid electromagnetic nanomaterial, which is a matrix based on a conjugated polymer of poly-3-amine-7-methylamine-2-methylphenazine with dispersed magnetite nanoparticles immobilized on multi-walled carbon nanotubes, has been synthesized. In situ magnetometry was used to study the kinetics of the hydrogen reduction of Fe3O4 immobilized in the structure of a ternary nanocomposite in magnetic fields of different intensities. An increase in the magnetite reduction reaction rate with the formation of metallic iron nanoparticles at T=420∘C and at a magnetic field strength in the range of 60–3000 Oe was observed. The dependence of the degree of conversion of Fe3O4 on the magnetic field strength was established.

“…Metal nanoparticles often play a major role, giving nanocomposites distinctive properties. In particular, the nature and composition of these nanoparticles largely dictate the catalytic [34,35], magnetic [36,37], photocatalytic [38], electrochemical [39][40][41], sensory [42], and antibacterial [43] characteristics of nanocomposite materials.…”

Novel ternary hybrid polyphenoxazine (PPOA)-derived nanocomposites involving Co-Fe particles and single-walled (SWCNTs) or multi-walled (MWCNTs) carbon nanotubes were prepared and investigated. An efficient one-pot method employing infrared (IR) heating enabled the formation of Co-Fe/CNT/PPOA nanocomposites. During this, the dehydrogenation of phenoxazine (POA) units led to the simultaneous reduction of metals by released hydrogen, yielding bimetallic Co-Fe particles with a size range from the nanoscale (5–30 nm) to the microscale (400–1400 nm). The synthesized Co-Fe/CNT/PPOA nanomaterials exhibited impressive thermal stability, demonstrating a half-weight loss at 640 °C and 563 °C in air for Co-Fe/SWCNT/PPOA and Co-Fe/MWCNT/PPOA, respectively. Although a slightly broader range of saturation magnetization values was obtained using MWCNTs, it was found that the type of carbon nanotube, whether an SWCNT (22.14–41.82 emu/g) or an MWCNT (20.93–44.33 emu/g), did not considerably affect the magnetic characteristics of the resulting nanomaterial. By contrast, saturation magnetization escalated with an increasing concentration of both cobalt and iron. These nanocomposites demonstrated a weak dependence of electrical conductivity on frequency. It is shown that the conductivity value for hybrid nanocomposites is higher compared to single-polymer materials and becomes higher with increasing CNT content.
