Abstract

Single-walled carbon nanotube (SWNT) density and bundle size has been controlled by a simple one step CVD growth process using a polyferrocenylsilane block copolymer as the pre-organized catalyst source.{ Electronic supplementary information (ESI) available: synthesis of PS-b-PFEMS, SWNT growth and characterization.

“…[128][129][130] The iron-rich ceramics from films of PS-b-PFS {28a (R = Me, R′= Et)} have been shown to catalyse the growth of single-walled carbon nanotubes (SWCNT). Typically, thin films were self-assembled, treated with UV-ozone to remove organic materials and subsequently used for simple one step chemical vapor deposition (CVD) growth of SWCNTs.…”

“…The purity of SWNTs is confirmed by a weak D mode in the Raman spectrum. 27 SWNT density is optimized by controlling the polymer film thickness to create three to six tube bundles per 100 m 2 , which provides a high density of separated and relatively disentangled tubes, therefore increasing the device sensitivity. A consistent and nearly uniform SWNT surface coverage in our approach allows for the direct deposition of metal electrodes onto the silica/nanotube surface without tedious positioning of the metal contacts or patterning of the catalyst to localize the nanotube growth.…”

“…Shell-crosslinked micelles have also been aligned and patterned on silicon substrates by microfluidic techniques, which may have interesting applications as magnetic memory materials or catalysts after pyrolysis. [291][292][293] PFS shell-crosslinked nanotubes have been shown allowing potential for encapsulation of guest particles or compounds within the hollow of the nanotube via in-situ redox reaction using PFS as a reductant. 344,346,366 Silver nanoparticles were prepared within the nanotubes through reaction with Ag[PF6].…”

“…[291][292][293][294] PS-b-PFEMS thin films were self-assembled and treated with UV-ozone to remove volatile organics and convert non-volatile inorganics into SiO2 and Fe2O3. After pyrolysis, the films were used for chemical vapour deposition (CVD) growth of SWCNTs, which were subsequently characterised by scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy.…”
