Preparation of Polyacrylonitrile/Graphene Oxide Nanocomposite-Derived Carbon Microstructures by Ion Beam Patterning and Post-Pyrolysis
In this study, the preparation of carbon microstructures (CMs) from polyacrylonitrile (PAN)/graphene oxide (GO) nanocomposites is described based on the ion beam patterning and pyrolysis. Thin films of PAN/GO nanocom-posites formed by spin-coating on a SiO2-deposited Si wafer were selectively irradiated through a pattern mask with 150 keV H+ ions at various fluences ranging from 1 × 1015 to 1 × 1016 ions/cm2, and subsequently developed with N,N´-dimethylformamide (DMF) to form PAN/GO patterns. The resulting PAN/GO patterns underwent a heat treatment process for the creation of CMs. Well-defined negative-type PAN/GO patterns were created at a fluence of 1 × 1015 ions/cm2, and they were pyrolyzed at 1000 °C without a significant shrinkage in the horizontal direction. The PAN/GO patterns were transformed into the graphitic CMs during the pyrolysis. Moreover, the formed CMs exhibited the GO content-dependent electrical conductivity in comparison to that of the pure PAN-derived CMs.
