Abstract

Battery and ultracapacitor electrodes are traditionally made with at least one polymeric binder material that mechanically holds the various, powder like, raw materials together. In addition to increasing the electrode resistance, the binder is assumed to be at least partially responsible for the performance degradation over time for rechargeable Lithium batteries.

We present here for the

Introduction
The field of nanocarbon-based composite materials is naturally driving and stimulating applied research today because of the high potentialities offered by both nanotechnology and carbon: each nanocarbon species (nanotubes, nanocones, nanowalls, graphene and graphite nanoplatelets, fullerenes and carbon nanodots, etc.) presents its own specific physico-chemical properties and reacts and performs differently under the same conditions, thereby enabling the optimization of material properties for specific applications (energy storage, water

ABSTRACT

Electromagnetic interference (EMI) shielding relates to the property of a material that acts as a barrier to the penetration of electromagnetic radiations. EMI shielding plays an important role in fields of application where electromagnetic waves, especially at high frequencies, can interfere with electronics. Applications of EMI shielding span from cellular phones and computers

Abstract

Graphene, in its one atom thick carbon sheet form, is a special 2 dimensional nanomaterial that bridges the chemical and physical worlds. On the one hand, graphene can be seen as a chemical, a gigantic two-dimensional monomer, allowing organic chemistry to investigate its use as a reactive platform and composite and polymer science to investigate its functionalized forms into dispersed, percolated or continuous architectures, ranging from randomly to highly

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

Raman spectroscopy is commonly used as a standard quality analysis technique for graphene characterization since it allows unambiguous, high-throughput, nondestructive identification of the number of graphene layers. It also allows to qualify defect, doping, strain, disorder and chemical modifications levels, as well as to locate grain boundaries of graphene. Many of these quality parameters need to be monitored during process and/or

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
