Precursors for Precursors: Few-Layer Graphenes

Few-layer graphenes are nanomaterials consisting of multiple layers of single-atom thick carbon sheets, known as graphene, that are stacked on top of each other.  Due to interlayer interactions, properties of few-layer graphenes can differ from those of the single-layer graphene, but they are also different from the properties of the bulk conventional graphite.  

ProChem Inc. has recently introduced two new products that are composed of 3 to 9 layers of graphene and are suitable for diverse materials science applications. 

Thus, enhanced materials performance with addition of Fractal Graphene, Nanoplatelets, product # 1944-1 has been observed in several technology areas, which include but are not limited to corrosion prevention, thermal conductivity, lubricity, hydrophobicity, electrical conductivity, and durability.

 

At the same time, Reactive Edge Oxidized Graphene, product # 1944-2, could be successfully incorporated into various materials and formulations with long-term stability, such as aqueous and non-aqueous dispersions, silicone and polyurethane composites, graphene inks and more.

Both products are offered as catalog products and are also available in bulk quantities and as customized materials.
