“…It possesses a high efficiency response towards visible light, a high carrier mobility, and an excellent thermal and chemical stability. Recently, by looking into these advantages, Saheeda and Jayaleksmi (2020) [ 216 ] successfully synthesized a nanocomposite of PPy and MWCNTs via liquid/liquid interfacial polymerization. In this study, they found that a strong interfacial interaction between the polymer and MWCNTs occurred.…”

A novel class of carbon nanotube (CNT)-based nanomaterials has been surging since 1991 due to their noticeable mechanical and electrical properties, as well as their good electron transport properties. This is evidence that the development of CNT-reinforced polymer composites could contribute in expanding many areas of use, from energy-related devices to structural components. As a promising material with a wide range of applications, their poor solubility in aqueous and organic solvents has hindered the utilizations of CNTs. The current state of research in CNTs—both single-wall carbon nanotubes (SWCNT) and multiwalled carbon nanotube (MWCNT)-reinforced polymer composites—was reviewed in the context of the presently employed covalent and non-covalent functionalization. As such, this overview intends to provide a critical assessment of a surging class of composite materials and unveil the successful development associated with CNT-incorporated polymer composites. The mechanisms related to the mechanical, thermal, and electrical performance of CNT-reinforced polymer composites is also discussed. It is vital to understand how the addition of CNTs in a polymer composite alters the microstructure at the micro- and nano-scale, as well as how these modifications influence overall structural behavior, not only in its as fabricated form but also its functionalization techniques. The technological superiority gained with CNT addition to polymer composites may be advantageous, but scientific values are here to be critically explored for reliable, sustainable, and structural reliability in different industrial needs.

“…Most of the samples with exception of 8 wt% of synthesized and 1 and 6.5 wt% of commercial MWCNTs and incorporated into PANI had lower I D /I G ratio than that reported by Shao et al [ 107 ], (I D /I G = 1.08) and Thakur et al (I D /I G = 1.14) [ 108 ], for PANI grafted on the surface of MWCNTs and PANI/CNT, respectively. These results highlight that the optimization of CVD parameters helps to reach a better structural order and it can modify the interaction-type between PPy and functionalized MWCNTs [ 109 ].…”

“…The differences between both polymers are due to the number of functional groups that lead to electrons transfer in a more efficient way between carbon atoms [ 118 ], which in turn is more effective in PPy than PANI matrix. The percolation behavior of CNTs in a PPy matrix has been found above 8.4 wt% of CNTs, depending on the synthesis parameters [ 109 , 118 ], but in this case, the best condition was attained with 6.5 wt% for PPy and 20 wt% for PANI. These differences at room temperature can be related to the dispersion during the pellet fabrication and temperature operation.…”

In this work, the optimal conditions of synthesizing and purifying carbon nanotubes (CNTs) from ferrocene were selected at the first stage, where decomposition time, argon fluxes, precursor amounts, decomposition temperature (at 1023 K and 1123 K), and purification process (HNO3 + H2SO4 or HCl + H2O2), were modulated through chemical vapor deposition (CVD) and compared to commercial CNTs. The processing temperature at 1123 K and the treatment with HCl + H2O2 were key parameters influencing the purity, crystallinity, stability, and optical/electrical properties of bamboo-like morphology CNTs. Selected multiwalled CNTs (MWCNTs), from 1 to 20 wt%, were electropolymerized through in-situ polarization with conductive polymers (CPs), poly(aniline) (PANI) and poly(pyrrole) (PPy), for obtaining composites. In terms of structural stability and electrical properties, MWCNTs obtained by CVD were found to be better than commercial ones for producing CPs composites. The CNTs addition in both polymeric matrixes was of 6.5 wt%. In both systems, crystallinity degree, related to the alignment of PC chains on MWCNTs surface, was improved. Electrical conductivity, in terms of the carrier density and mobility, was adequately enhanced with CVD CNTs, which were even better than the evaluated commercial CNTs. The findings of this study demonstrate that synergistic effects among the hydrogen bonds, stability, and conductivity are better in PANI/MWCNTs than in PPy/MWCNTs composites, which open a promissory route to prepare materials for different technological applications.

The results of studies in the field of interfacial synthesis and interfacial formations in liquid–liquid systems are summarized. The mechanisms of the processes of interfacial synthesis are considered. Data on the self-assembly of nanoparticles, films, and 3D materials are given. The properties of materials of interfacial formations in systems with rare-earth elements and di(2-ethylhexyl)phosphoric acid, obtained both in the presence and absence of local vibrations, are described. It was established that materials obtained in the presence of local vibrations in the interfacial layer have higher density, melting point, and magnetic susceptibility and lower electric conductivity. The effect of force field parameters on the properties of interfacial formations is considered. Practical applications and prospects for research in the field of interfacial formations are discussed.
