제목 The Optoelectrical Properties of Few-Walled Carbon Nanotubes/Silane Sol Hybrid Thin Films: Effects of the Silane Sol and the Bundle Size of the Carbon Nanotubes
초록 We discuss the effects of intermolecular interactions at the few-walled carbon nanotubes (FWNTs)/binder interface and the bundle size of the acid-treated FWNTs on the optoelectrical properties of FWNTs/silane sol hybrid films. The bundle size of the FWNTs was successfully controlled by using acid treatment; assembled bundle structures due to hydrogen bonding were observed only for FWNTs functionalized with hydroxyl groups (FWNTs-OH). Tetraethylorthosilicate (TEOS) and methyltriethoxysilane (MTMS) sols were used to manipulate the intermolecular interactions between the nanotubes and binder. In particular, in the FWNTs-OH/TEOS system, the sheet resistance decreases with increases in the amount of TEOS sol. This result is explained in terms of the densification of the bundled network structure of the FWNTs-OH in the presence of the unfavorable TEOS sol.
