| Outline of Final Research Achievements |
Independently controlling the number density and diameter of Fe nanoparticles (FeNPs) used as a catalyst for vertically aligned carbon nanotube (VA-CNT) growth is difficult by conventional methods. In this study, mixed solutions of no amphiphilic FeNPs and saturated fatty acid used as filler molecules were prepared to prevent the thermal aggregation of FeNPs and control the number density of VA-CNTs. FeNPs mixed with saturated fatty acid monolayer films were prepared on the water surface and deposited on SiO2/Si substrates by the Langmuir-Blodgett (LB) technique. VA-CNTs were synthesized by a thermal chemical vapor deposition method using acetylene gas. By controlling the ratio of FeNP catalyst to saturated fatty acid as a filler molecule in the LB film and optimizing hydrogen reduction condition, we were able to control the number density and diameter of FeNPs independently.
