Description
도 2A 및 2B는 적합한 그라파이트 출발 물질의 일례인 나노플레이트리트 스택의 TEM 상들이며, 여기에서 상기 상들은 종결된 표면 외에, 그래핀 층들의 수직이고 연속적인 특징을 명백히 나타낸다.
도 3은 하전되지 않은 그라파이트 나노플레이트리트의 SEM 상이며, 여기에서 섬유들이 3.35 Å의 그라파이트 면간격으로 상기 섬유들의 축에 수직으로 성장한 그라파이트 층("플레이트리트")을 포함함을 볼 수 있다.
도 4는 규소 상에서 건조된, THF 중의 0.01 중량% 칼륨-하전된(KC24) 나노그라파이트의 SEM 상(4.85x 배율)으로, 원래의 나노그라파이트 출발 물질과 대조적으로, 개별적인 편평한 종들을 도시한다.
