Ion implantation technique was employed to introduce iron nanoparticles (Fe NPs) into a carbon precursor polymer with the aim for formation of graphitic nanostructure through catalytic graphitization by the introduced Fe NPs. A phenolic resin was implanted by 100 keV Fe+ ions with ion fluence of 1E14-1E16 ions/cm^2 at ambient temperature under vacuum, and subsequently heat-treated at 800°C in nitrogen gas atmosphere. It was found that the particle size of Fe NPs could be controlled in the range of 5-30 nm by the Fe+ ion fluence. Additionally, it was found that nano-sized turbostratic graphite structure with mean interlayer distance of 0.3531 nm, which is consisted of shell-like carbon layers and intricately distorted carbon layers, was formed around the Fe NPs. The ion implantation technique is one of the advantageous ways to introduce size-controlled fine metal NPs which are effective for the formation of graphitic nanostructure from a carbon precursor polymer.
