We report first method for the preparation of 2D single-walled carbon nanotubes (SWNTs) structures using smectic LCs, 4’ hexyloxy-biphenyl-4-carboxylic acid ethyl ester. SWNT sheets were simply prepared via π-π stacking between small molecular liquid crystal exhibiting lamella structure at room temperature and SWNTs walls. The small molecular liquid crystal was found to be a self-organizing template for the formation of the 2D nanostructure. Differential scanning calorimetry (DSC), polarized optical microscopy (POM), X-ray diffraction (XRD) and scanning electron microscopy were used to characterize and confirm SWNT sheets. |
