Patterned Growth and Contact Transfer of Well-Aligned Carbon Nanotube Films

Abstract

The preparation of aligned and/or micropatterned carbon nanotubes is important to applications ranging from nanocomposites to field-emitting displays. By pyrolysis of iron (II) phthalocyanine under Ar/H2 at 800−1100 °C, we have synthesized large arrays of vertically aligned carbon nanotubes on various substrates, including quartz glass plates, from which substrate-free films were obtained simply by immersing the nanotube-deposited quartz plates into an aqueous hydrofluoric acid solution. Micropatterns of the aligned nanotubes suitable for device fabrication were generated either by patterned growth of the nanotubes on a partially masked/prepatterned surface or through a contact printing process involving region-specific transfer of the substrate-free nanotube films to other substrates (e.g., polymer films), which otherwise may not be suitable for nanotube growth at high temperatures.

Carbon nanotubes for organic/inorganic hybrid solar cells

“…It has been studied and refined over the years and may therefore offer many advantages [74,76]. However, ITO tend to fracture by deformations, so, they are not really suitable for using in flexible solar cells.…”

One-dimensional nanomaterials synthesized using high-energy ball milling and annealing process

“…Detailed experimental procedure can be found in [32,33]. When the temperature increases up to 1200 1C, SiCNWs with a typical diameter of 40 nm were produced and some were in well-aligned bundles as shown in Fig.…”

Methods of surface chemical patterning

“…За счет капиллярных взаимодействий штамп переносит раствор на обрабатываемую поверхность. В настоящее время микроконтакт-ная печать может быть использована для переноса практически любого материала: металлов [19], полимеров [20], биоматериала [21], различных наноструктур [22,23].…”

“…Nowadays microcontact printing can be applied to transfer almost any material, e.g. metals [19], polymers [20], biomolecules [21], different nanostructures [22,23].…”
