Overview | Product Information | Related Products
Graphene dispersion at Ossila is a homogeneous colloidal solution of graphene in organic solvent. They are predominantly single layer graphene in dispersion.
Graphene dispersion is one of the most convenient ways to handle graphene materials since graphene powers are lightweight and problematic to handle. Chemical vapor deposition (CVD) method has been employed to achieve a smooth continuous graphene single or few-layer film however CVD is an expensive and energy demanding process. Graphene dispersion is ready to be deposited on different substrates via solution processing techniques such as spin, spray, dip, and slot-die coatings. Graphene dispersion can also be easily diluted, with the help of sonication if necessary to break the aggregates and maintain a high ratio of graphene monolayers.
With excellent physical and chemical properties and being described as the strongest materials ever measured, graphene is a truly wonderful material offering great high electron mobilities of over 200,000 cm2 V− 1s− 1 at electron densities of ~ 2 × 1011 cm− 2, high thermal conductivity of ~ 5 × 103 W m− 1 K− 1.
Graphene dispersion in water or N-methyl-2-pyrrolidone (NMP) offers the opportunity to process the graphene materials at ease in a certain concentration at atomic structure level. They can also be solution processed with other materials, i.e. PEDOT:PSS, metal oxides or cement to form composite materials to change or reinforce the physical and chemical properties of other materials. Graphene dispersion can also be freshly diluted to the desired concentrations.
