Abstract

Single-walled carbon nanotube networks(SWNT-networks) were uniformly formed on a glass substrate by the dip-coating method. The changes of electrical and optical properties of SWNT-networks were investigated with respect to processing variables including number of dip, concentration of SWNT-colloidal solution, withdrawal velocity. Consequently, the sheet resistance and transmittance of the SWNTs-networks were sensitively controlled by the processing variables. The networks have highly uniform sheet resistance and optically excellent transmittance within the range of visible ray.

담지 방법을 통해 유리 기판 위에 단일벽탄소나노튜브 네트워크를 형성하였고, 코팅 공정변수(담지 횟수, 콜로이드 용액의 농도, 기판의 인출 속도)에 따른 탄소나노튜브 네트워크의 전기적 및 광학적 특성 변화를 관찰하였다. 그 결과 네트워크의 면저항 및 투과도는 코팅 공정변수들에 의해 민감하게 조절됨을 확인할 수 있었다. 탄소나노튜브 네트워크는 매우 균일한 면저항을 보이는 동시에, 가시광선 영역에서 우수한 투과도 특성을 보였다.
