ABSTRACT
This chapter presents the application of solution-based techniques in controlling the surface morphology and diameter of C60 fullerene nanowhiskers and nanotubes. The first technique involves the addition of polyaniline emeraldine base dissolved in N-methyl-2- pyrrolidone on fullerene nanowhiskers by direct-mixing to modify the surface texture. The second technique uses the liquid–liquid interfacial precipitation method and incorporates the combined effect of solvent and solvent ratio, incubation temperature, and photo-irradiation to control the diameter of fullerene nanotubes. Since the discovery of C60 fullerene solubility in benzene, they have been extensively used as precursor materials to synthesize a wide array of carbon-based nanostructures through the liquid–liquid interfacial precipitation method. The chapter discusses the variations in the morphological and structural characteristics resulting from changes in the synthesis parameters. The surface morphology of fullerene nanowhiskers can be modified by the incorporation of the conducting polymer polyaniline.
