▎ 摘 要
NOVELTY - A particle comprises stacked sub-structures in which each sub-structure includes stack of graphene layers and separation between successive stacked sub-structures is greater than separation between successive graphene layers in each sub-structure. USE - A particle for particulate material used for composite material, particle dispersion and article (all claimed). ADVANTAGE - Friability is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) particulate material comprising the particles; (2) manufacture of particulate material which involves subjecting starting material to plasma treatment; (3) composite material comprising particulate material which is dispersed in matrix material; (4) particle dispersion comprising particulate material which is dispersed in liquid medium; and (5) article comprising particulate material.
