Abstract
스테인리스 스틸 메쉬 표면을 환원 전처리하여 그 표면상에 직접 탄소나노튜브 또는 탄소나노섬유와 같은 VGCF (vapor grown carbon fiber) 나노물질을 합성 성장시켰다. 수소 가스를 이용하여 스테인리스 스틸 메쉬를 환원 처리함으로써, 금속 표면상에 bi-modal 분포의 작은 촉매입자와 큰 촉매입자들이 함께 생성되었다. 환원된 스테인리스 스틸메쉬로부터 VGCF의 합성 시, 수소 가스가 공급되지 않은 경우는 작은 촉매입자로부터 탄소나노튜브들이 주로 성장 되었으나, 특정 량의 수소 가스가 공급될 경우 큰 촉매입자로부터 탄소나노섬유들이 주로 성장되었다.
Vapor grown carbon fiber (VGCF) nano-materials such as carbon nanotubes and carbon nanofibers were directly grown on the surface of the stainless steel mesh pre-treated by reduction. The reduction of the stainless steel mesh by hydrogen formed small catalytic particles and large particles with bi-modal distribution on the metal surface. When the VGCFs were synthesized on the reduced mesh, carbon nanotubes (CNTs) were dominantly grown from the small catalytic particles without supplying hydrogen gas. However, carbon nanofibers (CNFs) were dominantly grown from the large catalytic particles with hydrogen.
