Graphene Flower Paste
Conductive carbon fillers are in various electronics-related products as materials that impart conductivity to insulating polymer materials, as electronic carrier materials (conductive paths) for power sources such as secondary batteries and fuel cells, and as catalyst carriers. As a filler for composite material, Graphene Flower® Paste has excellent strength, elastic modulus, flexibility, aspect ratio, electrical conductivity and thermal conductivity.

Example of Mixing with Resin
Graphite or Graphene Flower® Paste were added to phenol resin (BellPearl® S870 manufactured by Air Water BellPearl Co., Ltd.) in liquid/solvent, filtered, and then molded by hot pressing. While changing the amount of filler added, the volume resistivity and the in-plane thermal conductivity were measured and evaluated.
With regards to electrical conductivity, conduction is not observed with graphite unless 10% or more is added. But with graphene paste, electric conduction is observed even with a small amount of addition (2%). Regarding thermal conductivity, it increases to 3 W/m K, 12 W/m K and 70 W/m K with 10%, 20% and 60% addition of Graphene Flower® Paste, respectively. Compared with graphite, the same thermal conductivity can be observed with about 1/3 of the amount of Graphene Flower® Paste.
