Abstract

In recent years, exceptional physical and chemical properties of graphene have been demonstrated and widely acknowledged. Graphene films synthesized by Chemical Vapor Deposition (CVD) with different configurations (monolayer, bilayer, multilayer, etc.) and grain sizes (up to cm size) were developed to offer a wide range of electrical and chemical properties facilitating their application in several fields. This led to numerous investigations on the potential use of CVD

Abstract

Graphene and other 2D materials can be produced by chemical vapor deposition (CVD) processing.  CVD processing can also be used to manufacture many 1D nanomaterials such as carbon nanotubes and silicon nanowires as well as for a wide range of film depositions and other related surface modifications.  The related CVD substrates can be rigid or flexible, and can be in continuous rolls or discrete stacks.

Abstract

Our standard large area (> m2) CNTSheet™ manufacturing process produces anisotropic porous carbon nanotube sheets in the 10-200μm thickness range. They have electrical and thermal properties that are uniform in the “X” and “Y” direction (sheet plane) and are 1-3 orders of magnitude lower in the “Z” direction. This manufacturing platform, using mm long VASWCNT’s or VAMWCNT’s as the primary mechanically interlocking fiber material, allows

Abstract

Graphene, a 2D sp²-hybridized carbon sheet with one-atom thickness, has attracted increasing attention in recent years because of its unique structure and special properties. Recently several research publications have described the synthesis of 3D CVD graphene continuous networks^1,2 grown on Ni foam substrates and their utilization for various novel products and application developments such as high sensitive gas sensor³, electrode or electrode additive for solar cells⁴ and ultra capacitors.⁵

Abstract

Continuous interest in Graphene materials has been recently reinforced with the awarding of the Nobel Prize in Physics, 2010. Graphene materials are considered for use in a wide variety of practical applications including electronics, solar cells, MEMS and NEMS, as well as chemical and biological sensors. Our joined team has successfully grown graphene films on Ni and Cu using Chemical Vapor
