General description

Multi walled carbon nanotubes (MWNTs, CNTs) was prepared by plasma enhanced chemical vapor deposition (PECVD). The CNTs formed can be formed in bundles over a catalyst support or in patterns over substrates.1 Each MWCNT is tipped with nickel-catalyst particle with diameter equal to diameter of the nanotube.

Application

High quality CNT arrays suitable for nanoelectronics

Features and Benefits

Each MWCNT is tipped with nickel-catalyst particle with diameter equal to diameter of the nanotube.

Packaging

Packaged in Vacuum Release (VR) Trays. See Technical bulletin AL-237.

Carbon nanotubes are materials that possess remarkable properties and offer extraordinary possibilities.

Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.

Graphene's unique properties spark interdisciplinary interest; its honeycomb structure offers electrical, optical, and mechanical marvels.
