FE-SEM, TEM, AFM images and height profile of the exfoliated nanosheets. (a) FE-SEM and (b) TEM micrographs showing morphologies of the nanosheets exfoliated from LRH-oleate (x = 0.035). The AFM images (c,d) and the height profile (e) along the red line marked in (c), respectively. The inset in (a) shows the appearance of a colloidal suspension of the nanosheets in toluene, with a clearly observable Tyndall effect under laser beam irradiation. The inset in (b) is the SAED pattern of an individual unilamellar nanosheet.
