Synthesis of composites by doping of CNTs with nano Fe particles and its ignition through photo flashing

Fe-CNTs composite was synthesised by doping of MWCNTs (multi walled carbon Nano tubes) with Nano Fe particles. Initially the received CNTs were purified and activated by functionalization with OH and COOH groups. Then CNTs were doped with various Fe concentrations by simply adjusting weight (wt) ratio of Ferrocene. The composite was ignited by exposing it to an ordinary photo camera flash. It was observed that ignition of the composite was achieved with minimum 16% Fe concentration by wt. The composite was characterized by using FTIR, EDS, FE-SEM, TG/DTA and XRD techniques. Fe-CNTs composite displayed its decomposition around 350 degrees C instead of 600 degrees C as compared to the oxidation of as received or pristine CNTs. In that study a novel and versatile technique was engineered to synthesise the composite, which may also be used for adsorbing many other metals on the surfaces of CNTs for their application in numerous fields.
