In this work, the preparative conditions for optimizing growing carbon nanotube thin films on silicon wafers using an in-house chemical vapor deposition system was evaluated. We found that, when acetylene was used as the carbon source and nickel as the catalyst, the amount of carbon nanotubes grown on the silicon wafers was increased when the growth temperature was decreased from 800°C to 600°C. The...
In this study, we used four different hydrazines to react with CNTs to prepare CNT-based inks. We found that the ink with CNTs subjected to the 2,4-dinitrophenylhydrazine treatment exhibited much better dispersion property than the inks with CNTs treated with other organic hydrazines. In other words, within 3 days, all ink dispersions began to bundle and precipitate after the sample vials were left...
