“…KNT ipliklerin mukavemeti karbona benzer olup, kopma işleri yani toklukları (27 J/g) karbon lifinin yaklaşık iki katı iken elastik modülü ise nispeten daha düşük-tür. Ayrıca %6 uzama ve 20 saat sonunda KNT ipliklerde sürünme davranışı gözlenmemekte, 1 saat süreyle 450 C'de mukavemet ve esneklik korunmaktadır [16].…”

Here we explore the use of two-and three-dimensional scaffolds of multi-walled-carbon nanotubes (MWNTs) for hepatocyte cell culture. Our objective is to study the use of these scaffolds in liver tissue engineering and drug discovery. In our experiments, primary rat hepatocytes, the parenchymal (main functional) cell type in the liver, were cultured on aligned nanogrooved MWNT sheets, MWNT yarns, or standard 2-dimensional culture conditions as a control. We find comparable cell viability between all three culture conditions, but enhanced production of the hepatocyte-specific marker albumin for cells cultured on MWNTs. The basal activity of two clinically relevant cytochrome P450 enzymes, CYP1A2 and CYP3A4, are similar on all substrates, but we find enhanced induction of CYP1A2 for cells on the MWNT sheets. Our data thus supports the use of these substrates for applications including tissue engineering, enhancing liver-specific functions, as well an in vitro model systems with enhanced predictive capability in drug discovery and development.

“…10 Lately, many studies have focused on the fabrication and characterization of CNT multi-yarns to determine their unique properties and to take advantage of these properties for further advancement. [11][12][13][14][15] CNT multi-yarns have numerous potential industrial applications, including high strength composite, photonic waveguides, transparent and flexible electrodes, electronic transducers/actuators, biosensors, and military use.…”

“…[10][11][12][13] Yu et al 16 reported that when 15 single-walled CNTs were bundled together and pulled, an average tensile strength of 30 GPa was measured. Zhang et al 17 stated that when a large number of CNTs were bundled and twisted together into a two-yarn with a diameter of around 10 mm, the strength of the CNT multi-yarn was reduced to 460 MPa.…”

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.
