Direct growth of carbon nanotubes on a plastic substrate

Carnahan D., Esposito D., Izrailit I., Vasenkov A.V., CFD Resarch Corporation, US

The deficiency of carbon nanotube (CNT) growth on temperature-sensitive substrates such as plastic tapes impedes the further progress in CNT electronics. We report a novel method that is able to offer the solution by selectively [...]

Multiscale modeling carbon nanotube growth on a supercapacitor electrode

Vasenkov A.V., CFD Research Corporation, US

Recently, the supercapacitors utilizing Carbon Nanotubes (CNTs) were reported. Currently, the fabrication of CNT-based supercapacitors involves manipulation of CNTs that is difficult and expensive owing to tiny size of CNTs. The direct deposition of well [...]

Novel Reactor Utilizing Selective Heating Catalytic Nanoparticles for Low-Temperature Growth of Carbon Nanotubes

Vasenkov A.V., Kolobov V.V., Carnahan D., CFD Research Corporation, US

Chemical Vapor Deposition (CVD) of carbon nanotubes (CNTs) and carbon nanofibers (CNFs) is a catalytically controlled synthesis requiring catalyst temperatures in excess of 700°C. The CVD synthesis is typically accompanied by significant substrate heating which [...]

Low-temperature growth of carbon nanofibers by selective heating of catalyst

Vasenkov A.V., Kolobov V.V., Melechko A.V, CFD Research Corporation, US

A critical technological challenge for many potential carbon-nanotubes (CNT) and carbon nanofibers (CNF) applications is to have a process for a direct synthesis of aligned/micropatterned CNTs/CNFs on temperature-sensitive surfaces. Currently there is no process that [...]
