Graphene paste
Descriptions
Graphene paste is a high concentration of graphene dispersion of a quantity of few-layered graphene dispersed in water or an organic solvent. The graphene can be uniformly and stably dispersed in the solvent, effectively overcome the stacking and agglomeration of graphene sheet layers, give full play to its excellent physical properties, with a wide range of application areas in mechanical enhancement, thermal and electrical conductivity.
Property
( a ) High solid content, high purity, high dispersion and strong stability.
( b ) High conductivity, high thermal conductivity and excellent mechanical properties.
Application
( a ) As a function of the modified materials for functional coatings, latex, etc.
( b ) As the conductive additive used in inks, electromagnetic shielding, antistatic and lithium-ion batteries.
