Global SO has developed its own process allowing to produce modern carbon nanomaterials of various types: graphene nanomaterials, carbon nanotubes of various lengths and diameters, and carbon nanofibers. These are produced using a catalyst originating from the same plant. The features of the catalyst and synthesis conditions can also be flexibly customized to have a nanomaterials production satisfying all requirements of any end user/customer. The process developed is now ready for further scaling.
In order to introduce carbon nanomaterials as functional additives (to increase the electrical conductivity, strength, etc. of various materials), we developed a process allowing to get stable dispersions of carbon nanomaterials of various types, including those not requiring dispersing additives, such as surfactants.
