this is from some months back, but its always good to reread interesting stuff

Test results of tires using graphene derived from plasma technology show:

•Higher grip braking reduced by 2 meters at 50 kph, which is a significant safety feature;

•Improved rolling resistance, which means longer free wheel & increased fuel economy. This is particularly important to fleet managers whose bottom line is highly dependent on fuel economy;

•Comparison of graphene tires to a premium brand tire showed that the graphene tires outlasted the premium non-graphene tires by approximately 5,000 kilometers in real world road conditions; and,

•Cost-effective as compared to carbon black.

Graphene is used as a substitute to carbon black, one of the 4 components of tires: rubber, nylon, steel and carbon black. Carbon black is mainly used as a reinforcing filler in rubber products.

The black color of tires comes from carbon black, a readily-available material with a superior surface to volume ratio that provides greatly improved wear characteristics and heat-dissipation capabilities when added to rubber compounds. Natural rubber is off-white in color, and in fact the first rubber tires were white. (Source: Wikipedia)

But graphene has a greater surface to volume ratio, which makes it more suitable as a filler in tires. Graphite is composed of many graphene sheets held together by Van der Waals forces to form rigid platelets several hundreds of nanometers thick. Because most of the graphene sheets in graphite which is formed of graphene stacks, are unable to interact with the polymeric matrix, its performance is limited unless they have been dispersed and functionalized, which means adding sticky molecules or atoms to its surface.

The dispersion of graphene from Perpetuus’ plasma technology permits to increase the functional role of graphene as a superior substitute for carbon black. Elastomer blends are prepared for realizing the maximum surface area along with empathetic matrix selective functionalization – facilitating the efficient mixing of graphene stacks into the tires elastomeric targeted matrix. Dispersion routes include high shear mixing melt intercalation & in situ polymerization.

The Agreement between the companies addresses the first Phase of the Project, with the other phases to be described in a joint venture agreement to be entered into between Gratomic and Perpetuus.
