GRAPHITE ARTICLE HAVING PREDETERMINED ANISOTROPIC CHARACTERISTICS AND PROCESS THEREFOR

摘要

The invention presented is a graphite article having predetermined anisotropic characteristics, as well as a process for preparing the article. More particularly, the article is prepared by a process involving determining the desired anisotropic characteristics for a finished flexible graphite article; intercalating and then exfoliating flakes of graphite to form exfoliated graphite particles; forming a substrate graphite article by compressing the exfoliated graphite particles into a coherent article formed of graphene layers; and producing a controlled directional alignment of the graphene layers in the substrate graphite article to provide a finished graphite article having the desired anisotropic ratio.
