“…Multifunctional CNT hybrid material possesses enhanced properties relative to pristine CNT material, and may outperform traditional material in the intended application. Pristine CNT can be doped with metals [ 41 ], polymers, ceramics, and various chemicals [ 38 , 42 ] to meet various application needs. As there is an increasing trend in making CNT hybrid materials, characterization of the material becomes an important factor.…”

Decades of extensive research have matured the development of carbon nanotubes (CNTs). Still, the properties of macroscale assemblages, such as sheets of carbon nanotubes, are not good enough to satisfy many applications. This paper gives an overview of different approaches to synthesize CNTs and then focuses on the floating catalyst method to form CNT sheets. A method is also described in this paper to modify the properties of macroscale carbon nanotube sheets produced by the floating catalyst method. The CNT sheet is modified to form a carbon nanotube hybrid (CNTH) sheet by incorporating metal, ceramic, or other types of nanoparticles into the high-temperature synthesis process to improve and customize the properties of the traditional nanotube sheet. This paper also discusses manufacturing obstacles and the possible commercial applications of the CNT sheet and CNTH sheet. Manufacturing problems include the difficulty of injecting dry nanoparticles uniformly, increasing the output of the process to reduce cost, and safely handling the hydrogen gas generated in the process. Applications for CNT sheet include air and water filtering, energy storage applications, and compositing CNTH sheets to produce apparel with anti-microbial properties to protect the population from infectious diseases. The paper also provides an outlook towards large scale commercialization of CNT material.

“…Another organization also mentions CNT sheet as being safe [ 85 ]. CNT pristine sheet was tested for particle release [ 41 ], where particles were monitored using a personal ultrafine particle (UFP) counter (PUFP C110, Enmont LLC, Cincinnati, OH). No cleaning or post-processing of the sheets was performed.…”

This paper describes innovative work in the manufacturing of carbon nanotube (CNT) fabric and tape and how these materials can be used in textiles and fashion apparel. The field of CNT fabric is new and this article discusses the potential commercial impact of CNT fabric, the manufacturing barriers that currently exist, and provides suggestions to push the field towards large scale commercialization. Areas under investigation for commercialization of CNT fabric, tape and yarn include flexible heaters, filter membranes, smart textiles, electrical machines, hybrid fabric, and biomedical wire.

Effect of a Metallocene Catalyst Mixture on CNT Yield Using the FC-CVD Process

et al. 2022

This work studies synthesis of carbon nanotube (CNT) sheet using the high temperature (1400 °C) floating catalyst chemical vapor deposition (FC-CVD) method. Three metallocenes—ferrocene, nickelocene, cobaltocene—and their combinations are used as precursors for metal catalysts in the synthesis process. For the carbon source, an alcohol fuel, a combination of methanol and n-hexane (9:1), is used. First, the metallocenes were dissolved in the alcohol fuel. Then, the fuel mixture was injected into a tube furnace using an ultrasonic atomizer with Ar/H2 carrier gas in a ratio of about 12/1. The synthesis of CNTs from a combination of two or three metallocenes reduces the percentage of metal catalyst impurity in the CNT sheet. However, there is an increase in structural defects in the CNTs when using mixtures of two or three metallocenes as catalysts. Furthermore, the specific electrical conductivity of the CNT sheet was highest when using a mixture of ferrocene and cobaltocene as the catalyst. Overall, the multi-catalyst method described enables tailoring certain properties of the CNT sheet. However, the standard ferrocene catalyst seems most appropriate for large-scale manufacturing at the lowest cost.
