The superb mechanical and physical properties of individual carbon nanotubes (CNTs) provide the impetus for researchers in developing highperformance continuous fibers based upon CNTs [1]. The highest specific strength and stiffness reported for CNT fibers are, respectively, 5.3 times that of the strongest commercial fiber (T1000), and 4.3 times that of the stiffest commercial fiber (M70J) [2]....
Background and aim: In this study the cytotoxicity to human epithelial lung cells of single-walled carbon nanotubes, multi-walled carbon nanotubes and chrysotile was compared based on the following cytotoxicity indices: no observable adverse effect concentration (NOAEC), inhibitory concentration 50 (IC50), and Total Lethal Concentration (TLC). Materials and Methods: Human epithelial lung cells...
The aim of this work was to study the formation process of dielectrophoretic (DEP) carbon nanotube fibers (CNT-fibers) and characterize the fiber properties relevant to their technological applications. The fiber diameter was shown to increase when applied voltage was increased (up to 350 V(pp)) and when retraction speed was decreased (down from 400 µm s(-1)) in accordance with theoretical expe...
effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. an embedded carbon nanotube in a polymer matrix and its surrounding interphase is replaced with an equivalent fiber for predicting the mechanical properties of the carbon nanotube/polymer composite. the effects of an interphase layer between the nan...
