2-DTech offers graphene in hazard-free water dispersible form

This will have numerous commercial, logistical and safety advantages, thereby making the integration of graphene into next generation engineering designs much easier to accomplish.

Carbon nanomaterials, such as graphene nanoplatelets (GNPs), are often supplied as a liquid rather than a powder. Normally they will be suspended in organic solvents such as dimethylformamide (DMF) and N-methyl-2-pyrrolidone.

Unfortunately these solvents have several drawbacks. DMF’s chemical composition, for example, implies serious health concerns for workers involved in its handling (with links to cancer and birth defects).

In addition, it needs dangerous goods shipping certification, which adds to the expense and creates complications when it has to be transported. Furthermore, there are application issues to consider, as it cannot be used in conjunction with some types of plastics. 

IPA presents a more attractive alternative, as it does not have any of the previously mentioned drawbacks associated with DMF. When in solution with water it offers good stability for the graphene suspended within it.

Any risk of doping occurring is eliminated - thus assuring the quality of the graphene is maintained. Graphene supplied in this manner will stay stable at much higher concentrations over considerably long periods of time without being in anyway compromised.
