Carbon nanotube (CNT) devices and electronics are achieving maturity and directly competing or surpassing devices that use conventional materials. CNTs have demonstrated ballistic conduction, minimal scaling effects, high current capacity, low power requirements, and excellent optical/photonic properties; making them the ideal candidate for a new material to replace conventional materials in next-generation electronic and photonic systems. CNTs also demonstrate high stability and flexibility, allowing them to be used in flexible, printable, and/or biocompatible electronics. However, a major challenge to fully commercialize these devices is the scalable placement of CNTs into desired micro/nanopatterns and architectures to translate the superior properties of CNTs into macroscale devices. Precise and high throughput patterning becomes increasingly difficult at nanoscale resolution, but it is essential to fully realize the benefits of CNTs. The relatively long, high aspect ratio structures of CNTs must be preserved to maintain their functionalities, consequently making them more difficult to pattern than conventional materials like metals and polymers. This review comprehensively explores the recent development of innovative CNT patterning techniques with nanoscale lateral resolution. Each technique is critically analyzed and applications for the nanoscale-resolution approaches are demonstrated. Promising techniques and the challenges ahead for future devices and applications are discussed.

“…We demonstrate that this process can be used to pattern high-aspect ratio vertically aligned CNTs (VACNTs), resulting in submicron channels (diameters down to ∼100 nm) that are aligned perpendicularly to the substrate and with heights up to 330 μm. Patterning of CNT catalyst using colloidal lithography has been shown before by Mathur et al for pillars of ∼10 μm and by Man et al for lower height structures and their magnetic properties; this paper, however, focuses on the ability to form structures that reach aspect ratios of over 3000 and have the advantage of offering straight continuous pores without any internal dead-ends for a broad range of applications. Finally, we show how this process can be used for creating thick Li-ion battery (LIB) anodes with a good tortuosity.…”

Technological advances in membrane technology, catalysis, and electrochemical energy storage require the fabrication of controlled pore structures at ever smaller length scales. It is therefore important to develop processes allowing for the fabrication of materials with controlled submicron porous structures. We propose a combination of colloidal lithography and chemical vapor deposition of carbon nanotubes to create continuous straight pores with diameters down to 100 nm in structures with thicknesses of more than 300 μm. These structures offer unique features, including continuous and parallel pores with aspect ratios in excess of 3000, a low pore tortuosity, good electrical conductivity, and electrochemical stability. We demonstrate that these structures can be used in Li-ion batteries by coating the carbon nanotubes with Si as an active anode material.

Screen-Printed Electrodes Constructed Using Carbon Black as Conductive MaterialAbstract: The use of screen-printed electrodes has become attractive in the last years, mostly in function of its versatility and low-cost. In the present work, were developed screen-printed electrodes using a simple production methodology (silk-screen) and alternative materials (carbon black and acetate of cellulose). Screen printed electrodes prepared with 75% (m/m) of carbon black and 25% (m/m) of cellulose acetate had shown the best performance and they were employed for determination of ascorbic acid by chronoamperometry and cadmium and lead ions using anodic stripping voltammetry. Limit of detection of 3.1 x 10 -5 mol L -1 and relative deviation of 1.9% were found for determination of ascorbic acid and linear dynamic range from 8.0 x 10 -7 to 3.2 x 10 -5 mol L -1 and 1.0 x 10 -6 to 6.3 x 10 -5 mol L -1 were verified for cadmium and lead ions respectively.
