Abstract
An experiment on the process of producing vapor growth carbon fiber (VGCF) by thermal decomposition of benzene and catalyses, ferrocene and thiophene, is carried out in an atmosphere of hydrogen used as carrier gas. A quartz tube of 900 mm in length and 15.5 mm in inner diameter is used as a vertical tubular reactor. The heated zone of the reactor is 475 mm long. The mass and structural atoms of the produced VGCF is measured with an ultimate analyzer to evaluate the yield. The produced VGCF is observed with transmission electron microscopes (TEM) to evaluate the average diameter and its standard deviation by the modified Thompson-τ method. The effects of the conditions such as the amount of catalyses, the nozzle temperature and the heated length on the yield, the average diameter and its standard deviation of VGCF are examined. The growth mechanism and radial growth speed are also evaluated from TEM photographs.
