THE EFFECT OF CARRIER GASES ON CNTS GROWTH BY FLOATING CATALYSIS METHOD THROUGH PYROLYSIS OF FERROCENE
CNT arrays grew on macroporous substrate for different time in the ammonia and nitrogen carrier gases by floating catalyst method. Scanning electron microscope (SEM) and Transmission electron microscope (TEM) were used to characterize the morphology of the CNTs supported on porous substrate. Experim...

| Sumario: | CNT arrays grew on macroporous substrate for different time in the ammonia and nitrogen carrier gases by floating catalyst method. Scanning electron microscope (SEM) and Transmission electron microscope (TEM) were used to characterize the morphology of the CNTs supported on porous substrate. Experimental results show that the vertically aligned CNT could grow on the macroporous substrate. Carrier gases have obviously effect on the diameter and growth rate of CNTs. Both growth time and diameter of CNTs are the key factors to keep the vertically aligned CNTs growth. |
