Growth of carbon nanotube arrays using the existing array as a substrate and their Raman characterization

Large-Scale Synthesis and Characterization of Helically Coiled Carbon Nanotubes by Use of Fe(CO)5 as Floating Catalyst Precursor

“…The second-order modes are the D * line at 2695.2 cm -1 (overtone of D), the combination of D and G lines at 2931.4 cm -1 , and the G * line at 3209.4 cm -1 (overtone of D‘). The peak at 2447.0 cm -1 was frequently reported previously, − but the origin of it remains uncertain. Here, the peak 2447.0 cm -1 seems to be the combination of D line and the peak 1099.0 cm -1 (1349.9 + 1099.0 = 2448.9).…”

Carbon Nanotubes and Spheres Produced by Modified Ferrocene Pyrolysis

“…Synthesis and tailoring of different formations of carbon nanotubes makes necessary, therefore, the use of additional carbon sources. Various hydrocarbons, such as p -xylene, ,− acetylene, benzene, , and others, have proved to be suitable carbon dispensers in mixtures with a metallocene.…”

“…Recently, increasing work has been focused on growth methods leading to well-aligned CNTs over large areas to form nanotube arrays. With use of CVD, large CNT arrays were successfully grown on different substrates such as mesoporous silica, , quartz glass, ,, Au film, and existing CNT arrays, under the catalytical activity of Fe, Ni, or Co. The alignment of nanotubes is highly desired for potential applications in vacuum microelectronics and flat panel displays. ,, CNTs filled with ferromagnetic material are of particular interest for the development of data storage systems, toners, and inks for xerography …”

Poly(butylene cyclohexanedicarboxylate/diglycolate) random copolymers reinforced with SWCNTs for multifunctional conductive biopolymer composites

“…The new designed materials might possess the unique properties offered by the synergistic interaction of the nanostructures with the polymer matrix [14,15]. Carbon nanotubes (CNTs) have been considered as ideal reinforcing candidates for the production of multifunctional polymer composites, since they simultaneously display high aspect ratio and nanometer dimensions, and more importantly, extraordinary mechanical strength and high electrical and thermal conductivity [16][17][18][19]. However, in order to obtain the desired performance in the final composites, a tailored CNT dispersion in the polymers has to be reached and the strong Van der Waals interaction between the tubes [20,21] has to be overcome.…”
