“…3 The sp 2 bonds between the corresponding carbon atoms and densely packed honeycomb crystal lattice structure offer excellent mechanical (tensile strength of 150 GPa), thermal (1500-3000 W/mÁ K), and electrical (10 4 S/cm) conductivities of CNTs. 4 Because of these extraordinary properties, these materials are considered to be the next generation of materials for lighter aircraft, faster vehicles, more capable computers/satellites, more sensitive sensors, better micro-and nano-chips, fuel cells and solar cells, and batteries for different industrial applications, such as electronics, optics, medical, energy, chemical, defense, aircraft and spacecraft, etc. 2 Recently, there has been a considerable interest in stronger, lighter, flexible, and thermally and electrically conductive materials for aerospace applications.…”

The behavior of a carbon nanotube (CNT) multi-yarn consisting of 30 yarns and coated with a thin layer of polyester is investigated under tensile loading condition. The coated and uncoated CNT multi-yarns are loaded until fracture occurred inside a scanning electron microscope. In situ photographs were undertaken to investigate the helix angle, diameter, yarn twist, and damage and failure mechanisms. The coated CNT multi-yarn has a higher ultimate tensile strength than the uncoated counterpart. The coated multi-yarn fails at a single location and remains tight after the failure. The uncoated yarn fails at multiple locations along its length and also unravels. The adhesive coating adheres to the CNT yarn surface and does not penetrate into the yarn. These results provide insights into how CNT multi-yarn would behave when used as the reinforcement in the nanocomposites.

“…The difference between SWCNTs and MWCNTs is SWCNTs show single-layer of graphene sheet whereas MWCNTs consist of multi-layer of graphene sheets [21]. CNTs also can be used in many of fields, including chemical, mechanical, and electrical applications, due to their excellent characteristic properties [22][23][24][25]. In terms of theory, the structure of MWCNTs is very complex and much more difficult to confirm that that of SWCNTs.…”

Abstract-Composites of rice husks and carbon nanotubes (RHCNTs) are an innovation in improving the absorption of microwave signals. Rice husks, which are an agricultural waste material, have been found to possess a significant propensity for absorbing microwave signals. Studies have shown that both rice husks and carbon nanotubes (CNTs) have high percentages of carbon. Thus, in this paper, we present the results of our experimental study in which we varied the ratios of rice husks and CNTs in the composite materials and determined the dielectric properties of the composites and measured their abilities to absorb microwave signals. The experimental microwave

“…The poor solubility of carbon nanotubes in organic solvents restricts them to be used as drug delivery agents into living systems in drug therapy. Hence many modification approaches like physical, chemical or combined have been exploited for their homogeneous dispersion in common solvents to improve their solubility [1][2][3][4]. The reports appeared till now in the literature reveals that the modification is required to control the dispersion and such modification introduces specific functionalities as molecular wedges onto the surface of the carbon nanotubes.…”
