The main aim of this research work is in situ synthesis of carbon nano tube (CNT) on nonwoven glass mat. Different types of catalyst were used and the effect of them on growth of carbon nanotubes on glass mat was investigated. The process was considered as variable catalysts to achieve optimal conditions for CNT deposition on glass mat. In this research, iron, cobalt, copper and nickel were used as catalysts and acetylene gas was used as the hydrocarbon source. Also, argon was used as a carrier gas. In first step, samples were coated by mentioned catalyst using plasma sputtering method. The thickness of the catalyst on the surface of samples was fixed at 100 nm. In second part, thermal chemical vapor deposition (TCVD) system was used for growth of carbon nano tubes. Scanning electron microscopy (SEM) and raman spectroscopy, thermogravimetric analysis (TGA-DTG) and transmission electron microscopy (TEM) were used for investigating the morphology and quality of produced CNT. Electrical conductivity was observed and compared on both untreated and coated glass mat. The results show that, by pre sputtering of samples with nickel, the quality of CNT on the surface of glass mat will be improved and the resistivity of samples reach to 610 Ω.
