C60/Collapsed Carbon Nanotube Hybrids - A Variant of Peapods

2/11/2015

Our most recent work has been published in the journal of Nano letters. This time we introduced C60 fullerenes inside collapsed carbon nanotubes. The overfilling of the collapsed tubes allows a complete reinflation, where the C60 core shows a well defined crystalline structure. This work has been published as an open access, the file can be downloaded here.

Abstract

We examine a variant of so-called carbon nanotube peapods by packing C60 molecules inside the open edge ducts of collapsed carbon nanotubes. C60 insertion is accomplished through a facile single-step solution-based process. Theoretical modeling is used to evaluate favorable low-energy structural configurations. Overfilling of the collapsed tubes allows infiltration of C60 over the full cross-section of the tubes and consequent partial or complete reinflation, yielding few-wall, large diameter cylindrical nanotubes packed with crystalline C60 solid cores.
