    Abstract

    Coronene-based graphene nanoribbons encapsulated inside single-walled carbon nanotubes (SWNTs) were prepared 440°C under Ar and annealed at temperatures up to 825°C. The structural modifications of coronene/SWNT samples were studied using Raman spectroscopy and transmission electron microscopy. Coronene and coronene-based graphene nanoribbons are hydrogen terminated and annealing at temperatures above the stability limit of C-H bonds were expected to result in formation of new products. Indeed, Raman spectroscopy revealed the appearance of new sharp peaks after annealing of samples above 650°C. The possible nature of encapsulated products produced by annealing of hydrogen terminated nanoribbons inside SWNTs is discussed.
