“…In case of Young's modulus of the nanocomposites, adding 0.1 wt.% nanodiamond instigated improved Young's modulus, compared with the graphene or carbon nanotube nanofiller. The mechanical property enhancement was due to the interface formation and matrix-nanofiller interactions leading to load transference through the nanomaterial [119][120][121]. Improved properties were attributed to spherical shape and high surface area of nanodiamond, relative to other carbon nanoparticles.…”

Carbonaceous or nanocarbon nano-reinforcement nanocomposites have been found as emergent candidates for aerospace industry. Consequently, the multifunctional nanocomposites have been fabricated using marvelous nanocarbon nanostructures like graphene, carbon nanotube, fullerene, carbon black, etc. Manufacturing techniques have also been engrossed for the formation of high performance engineering nanocomposites having fine strength, heat stability, flame resistance, and other space desired features. These practices include solution, in situ, and melt procedures, on top of specific space structural design techniques, for the formation of aerospace structures. The aerospace related material property enhancements using various carbonaceous nano-reinforcements depends upon the type of nanocarbon, dimensionality, as well as inherent features of these nanostructures (in addition to the choice of manufacturing methods). Furthermore, carbon nano-reinforcements have been filled, besides carbon fibers, in the epoxy matrices. Nanocarbon coated carbon fibers have been filled in epoxy resins to form the high performance nanomaterials for space structures. The engineering features of these materials have been experiential appropriate for the aerospace structures. Further research on these nanomaterials may be a key towards future opportunities in the aero systems. Additionally, the explorations on structure-property relationships of the carbonaceous nanocomposites have been found indispensable for the development of advanced aerospace structures.

“…Having both electrical properties and magnetic response, with addition of possible flexibility and ease of synthesis, nanocomposites based on conducting polymers and magnetic nanoparticles are of high interest both in the scientific and commercial worlds [1,2]. Continuous studies aiming at a better understanding of their electrical properties, the influence of the filler, and the interface between components, on the final properties of the nanocomposite materials resulted in numerous reports showing new methods for their synthesis and potential applications [3][4][5][6][7][8].…”

In the presented study, we have synthesized six nanocomposites based on various magnetic nanoparticles and a conducting polymer, poly(3-hexylthiophene-2,5-diyl) (P3HT). Nanoparticles were either coated with squalene and dodecanoic acid or with P3HT. The cores of the nanoparticles were made of one of three different ferrites: nickel ferrite, cobalt ferrite, or magnetite. All synthesized nanoparticles had average diameters below 10 nm, with magnetic saturation at 300 K varying between 20 to 80 emu/g, depending on the used material. Different magnetic fillers allowed for exploring their impact on the conducting properties of the materials, and most importantly, allowed for studying the influence of the shell on the final electromagnetic properties of the nanocomposite. The conduction mechanism was well defined with the help of the variable range hopping model, and a possible mechanism of electrical conduction was proposed. Finally, the observed negative magnetoresistance of up to 5.5% at 180 K, and up to 1.6% at room temperature, was measured and discussed. Thoroughly described results show the role of the interface in the complex materials, as well as clarify room for improvement of the well-known magnetoelectric materials.

“…31,32 So, using a mixture of the two fillers is a superior technique to create antistatic composite materials when balanced against the benefits of carbon fillers (high conductivity) and ICP (cheap cost, good compatibility). [33][34][35] Among them, polyaniline (PANI) has become one of the most ideal ICPs for preparing composite materials because of its light weight, easy synthesis, high yield, adjustable conductivity, and high environmental stability. [36][37][38] There have been several reports about the use of CNT/PANI composites so far in a variety of sectors.…”

Emulsion polymerization was used to create composites of polyaniline‐amino‐carbon nanotubes (PANI‐A‐CNT). Fourier transform infrared spectroscopy (FT‐IR) was used to examine the chemical bonding properties of PANI and carbon nanotubes in composite materials. Transmission electron microscopy (TEM) was used to confirm that the PANI layer on the core‐shell structure of PANI‐A‐CNT material was nanoscale in size. In order to assess the impact of various carbon nanotube contents on the electrostatic and mechanical properties of the composites, pristine carbon nanotube/ABS (p‐CNT/ABS) and PANI‐A‐CNT/ABS composites were prepared. The mass fractions of PANI and CNT in PANI‐A‐CNT were 93.7 and 6.3 wt%, respectively, according to thermogravimetric analysis (TGA); hence, 4 wt% of PANI‐A‐CNT included 0.3 wt% CNT and 3.7 wt% PANI. The surface resistance test revealed that the PANI‐A‐CNT/ABS composite with 4 wt% PANI‐A‐CNT has a surface resistance of 108 Ω, which is one time less than the surface resistance of the p‐CNT/ABS composite with 4 wt% p‐CNT. Moreover, PANI‐A‐CNT/ABS composite (0–4 wt% PANI‐A‐CNT) has stronger tensile and impact properties than p‐CNT/ABS composite (0–4 wt% p‐CNT), expanding the range of applications for ABS resin.
