Abstract

L'invention concerne un film de graphène intégral comprenant des feuilles de graphène chimiquement fonctionnalisé qui sont liées ou interconnectées chimiquement les unes avec les autres ayant un espacement inter-planaire d?002#191 de 0,36 nm à 1,5 nm selon une détermination par diffraction de rayons X et une teneur en élément non carboné de 0,1 % à 47 % en poids, lesdites feuilles de graphène fonctionnalisé étant sensiblement parallèles les unes aux autres et parallèles à une direction dans le plan dudit film de graphène intégral et ledit film de graphène intégral ayant une longueur de 1 cm à 10 000 m, une largeur de 1 cm à 5 m, une épaisseur de 2 nm à 500 µm, et une densité physique de 1,5 à 2,25 g/cm3. Le film de graphène intégral a typiquement un module de Young de 20 GPa à 300 GPa ou une résistance à la traction de 1,0 GPa à 3,5 GPa. L'invention concerne également un procédé de production du film de graphème intégral.
