چکیده
Morphology of BMIM FAP on the heated mica surface Mica was cleaved and heat treated in an conventional oven at 120 C for 1 h. Afterwards, the mica was dip-coated with 0.01 g/L and 0.001 g/L BMIM FAP/Vertrel (2,3-dihydrodecafluoropentane) solution, respectively. The average thickness of the resulting BMIM FAP nanofilms is estimated to be in the order of angstrom or lowerS1. The topography of BMIM FAP/mica samples was characterized by AFM. As shown in Figure S2, for both 0.01 g/L and 0.001 g/L sample, very small droplets are clearly visible on the mica surface, indicating complete dewetting of BMIM FAP on the heated mica surface.

What causes extended layering of ionic liquids on the mica surface?
Extended layering of ionic liquids (ILs) on the mica surface has been reported by several groups previously and it is generally accepted that the electrostatic interaction at the IL/mica interface is critical to the observed extended layering. Here we report that, indeed, water adsorption on the mica surface is the key to the extended layering of ionic liquids. The atomic force microscopy (AFM)...

A unique, but unifying, feature of ionic liquids (ILs) is that they are nanostructured on the length scale of the ions; in many ILs well-defined polar and apolar domains exist and may percolate through the liquid. Near a surface the isotropic symmetry of the bulk structure is broken, resulting in different nanostructures which, until now, have only been studied indirectly. In this paper, in sit...
