Journal ArticleDOI
Load transfer and deformation mechanisms in carbon nanotube-polystyrene composites
TL;DR: In this paper, in situ transmission electron microscopy studies provided information regarding composite deformation mechanisms and interfacial bonding between the multi-wall carbon nanotubes and polymer matrix, indicating significant load transfer across the nanotube-matrix interface.
Journal ArticleDOI
Continuous production of aligned carbon nanotubes: a step closer to commercial realization
Rodney Andrews,David Jacques,Apparao M. Rao,Frank Derbyshire,Dali Qian,X. Fan,Elizabeth C. Dickey,J. Chen +7 more
TL;DR: In this paper, high-purity aligned multi-walled carbon nanotubes were synthesized through the catalytic decomposition of a ferrocene-xylene mixture at ; 6758C in a quartz tube reactor and over quartz substrates, with a conversion of ; 25% of the total hydrocarbon feedstock.
Journal ArticleDOI
Multiwall Carbon Nanotubes: Synthesis and Application
TL;DR: A simple method for purifying and healing structural defects in the nanotubes is described and the effects of reactor temperature, reaction time, and carbon partial pressure on the yield, purity, and size of the MWNTs produced are reported.
Journal ArticleDOI
Model of carbon nanotube growth through chemical vapor deposition
Susan B. Sinnott,Rodney Andrews,Dali Qian,Apparao M. Rao,Zugang Mao,Elizabeth C. Dickey,Frank Derbyshire +6 more
TL;DR: In this article, a model to account for the catalyzed growth of nanotubes by chemical vapor deposition is presented. But the model does not consider the physical dimensions of catalyzed reactions.
Journal ArticleDOI
Purification and structural annealing of multiwalled carbon nanotubes at graphitization temperatures
TL;DR: In this article, the effects of graphitization on the structural perfection of multi-walled carbon nanotubes were investigated and the results showed that the graphitisation procedure was able to remove residual metal catalyst in the nanotube and reduce the wall defects as reflected in reduced interlayer spacing between the graphene shells.
