The physical/chemical properties of carbon nanotube (CNT) have attracted much interest for applications in different fields, from microelectronic to photonic technology, due to their exiting conductivity properties, high hardness and high resistance to thermal stress. The technology to produce CNT with the desired properties is still under development. In this work, we report on fabrication CNT deposited by simple chemical route via the reaction between ferrocene and ammonium chloride in air at low temperature. UV–VIS absorption spectroscopy and Transmission Electron Microscopy (TEM) provide the experimental confirmation that CNT-like structures are present then our intention to get nanocomposites consist of CNTs and a poly methyl methacrylate by melt mixing process with high mechanical properties for principal concepts of the preparation of such materials for different applications.
