High-Performance Carbon Nanotube Fiber

Krzysztof Kozioł, Juan J. Vilatela, Anna Moisala, Marcelo Motta et autres

With their impressive individual properties, carbon nanotubes should form high-performance fibers. We explored the roles of nanotube length and structure, fiber density, and nanotube orientation in achieving optimum mechanical properties. We found that carbon nanotube fiber, spun directly and continuously from gas …

Growth, Characterization, and Potential Applications of Periodic Carbon Nanotube Arrays

Zhi Ren, Brian R. Kimball, J. Rybczyński, Zhiwei Huang et autres

Abstract : Periodically aligned carbon nanotube (CNT) arrays have been grown on Ni dots made by nanosphere lithography. Optical characterization reveals strong interaction between the nanotubes' surface and incident light. Periodic CNT arrays interact strongly with light because their feature size is …

PERMEATION BEHAVIOR AND PHYSICAL PROPERTIES OF NATURAL RUBBER NANOCOMPOSITES

Walter Zukas, M. Sennett, Elizabeth A. Welsh, A. Rodríguez et autres

Nanocomposites made by adding nanoparticle reinforcement to polymers have been demonstrated to have significantly enhanced properties at relatively low levels of added reinforcement. The observed properties have in some cases been attributed to the shape of the reinforcing particle. Nanoparticle additives with …

Carbon Nanotube-Polycarbonate Composites

Raouf O. Loutfy, James C. Withers, M. H. Abdel-Kader, M. Sennett

Carbon nanotubes were investigated as high-performance reinforcement for polymer composites. The inherently superior mechanical properties of nanotubes coupled with the high interfacial surface areas available to dissipate energy suggest that nanotube-polymer composites would have excellent potential as high-strength, impact-resistant materials. The multiwall …

Dielectric media based on isolated metallic nanostructures

Thomas J. Kempa, David Carnahan, M. Olek, Maria Camila Belduque Correa et autres

We study the dielectric properties of nanocomposites in the 0–1.5-GHz frequency regime. These composites consist of electrically insulated metallic nanoparticles and carbon nanotubes, the elongated nanostructures in this study, uniformly dispersed in a dielectric matrix. We find that the properties of these …
