Product Name

Graphene nanoplatelets (6-8 nm thick x 5 microns wide)

Structure

Category

Graphenes

Description

Graphene Nanoplatelets are flakes composed of multilayer graphene sheets in a "platelet" morphology. The unique shape with a high aspect ratio of thinness to width give them excellent electrical and thermal conductivity and make them ideal for applications such as strengthening composites and matrix materials, serving as barriers.
