NOVELTY - Continuously producing porous solid film of spacer-modified nano graphene platelets involves dissolving a precursor material in solvent to form precursor solution and dispersing nano graphene platelets to form suspension; continuously delivering and forming the suspension into layer of solid film composed of precursor material-coated graphene platelets overlapping one another and removing solvent from film; optionally continuously converting precursor material into nodules bonded to surfaces of platelets to form porous solid film; and continuously collecting film on collector. USE - For producing porous solid film of spacer-modified nano graphene platelets, which is useful as supercapacitor electrode (claimed). ADVANTAGE - The process produces the modified nano graphene platelets exhibiting a specific surface area greater than 500 (preferably greater than 900, especially greater than 1384, particularly greater than 2600) m2/g. DETAILED DESCRIPTION - Continuously producing a porous solid film of spacer-modified nano graphene platelets involves: (A) dissolving a precursor material in a solvent to form a precursor solution and dispersing multiple nano graphene platelets into the solution to form a suspension; (B) continuously delivering and forming the suspension into a layer of solid film composed of precursor material-coated graphene platelets overlapping one another, and removing the solvent from the solid film; (C) optionally continuously converting the precursor material into nodules bonded to surfaces of graphene platelets to form a porous solid film composed of spacer-modified graphene platelets; and (D) continuously collecting the porous solid film on a collector.
