The chemical vapor deposition (CVD) synthesis of magnetic carbon nanotubes (mCNT) using carbon dioxide/carbon catalyst has been successfully carried out in various pressures. The temperatures were set at 800° C for 10 minutes reaction time. Nitrogen (N2) gas in 20 Torr was flown in followed by ethanol vapor until the final pressure reached 80 and 100 Torr without added air, and 180 Torr with added air. The formation of mCNT was confirmed by shifted X-ray diffraction (XRD) peak of graphite from 26.53° to 25.53° which were highly considered to the other carbon allotropes with sp2 hybridized carbon atom hybridization structures. The higher pressure with added atmospheric air led to the excessive oxidation which influenced the growth of mCNT. Transmission electron microscopy (TEM) analysis observed mCNT filled by catalyst particles which suggested as magnetic phase induced the magnetic property of mCNT. The best electrical conductivity performance (lower electrical resistance) was owned by mCNT produced in the lower pressure condition with no air added.

“…The analysis of studies in the field of nanomodification showed that most of them are devoted to the modification of hydration hardening binders (Voitovich, Cherevatova, Zhernovsky, Fisher, & Sobolev, 2014;Alafogianni, Dassios, Tsakiroglou, Matikas, & Barkoula, 2019), polymeric and organic materials (Santagata, Baglieri, Tsantilis, & Chiappinelli, 2013), and to a lesser extent ceramic materials (Dillon et al, 2015). At the same time, synthesized carbon-based products, including various types of fullerenes, nanotubes, and graphenes, are suggested as an active modifying component (Korayem, Tourani, Zakertabrizi, Sabziparvar, & Duan, 2017;Hawreen & Bogas, 2019).…”

The article focuses on the study of influence of natural and man-made nanoformations (chrysotile fibers, carbon black, and graphite) on the formation of the structure of the material based on a hydraulic binder. The data on the positive effect of the optimal amount of modifying dispersions on the physical and technical properties of the samples were obtained. On average, the increase in compressive and bending strength, when using the considered additives, is from 10 to 40%. The results of the study of the microstructure and IR spectra of the check and modified compositions show that adding natural and man-made nanosystems provides optimal conditions for the formation of strong, dense new formations in the cement matrix. In general, the data obtained prove the effectiveness of their use in comparison with synthesized carbon nanosystems.

“…However, not all kinds of POSS possess great capacity with the epoxy matrix, and the nanoparticle of POSS may aggregate in the matrix. Fortunately, there are many ways to modify the surface property of nanoparticle , and fabricating nanoparticle into liquid‐like derivatives is an efficient method . The liquid‐like derivatives always have core, corona, and canopy structure.…”

Four kinds of liquid-like polyhedral oligomeric silsesquioxanes derivatives (liquid-Ds) were fabricated and characterized by FTIR, XPS, TGA, and Rheometer. The liquid-Ds/epoxy nanocomposites were prepared and their thermal resistance properties were tested by TGA. As a result, the thermal resistances properties were improved sharply and influenced by particle sizes, flow abilities, and bonding types of liquid-Ds. The glass transition temperature improved via adding liquid-Ds. The increase of crosslinking density was thought as an important factor to these improvements, which was studied by FTIR spectra and gel content of curved nanocomposites.
