Preparation method of high-density vertically-oriented graphene and thermal interface application of high-density vertically-oriented graphene
The invention discloses a high-density vertically-oriented graphene material as well as a preparation method and application thereof, and the high-density vertically-oriented graphene material is mainly characterized in that the high-density vertically-oriented graphene material is formed on a high-density active substrate through plasma enhanced chemical vapor deposition growth.
