Polarized optical microscopy image of a drying pattern containing SWCNTs and PFO. (a) The micrograph on a glass surface. (b) and (c) show the gray scale as a function of the azimuth angle for the glass surface and silicon wafer, respectively. (d) Gray scale of optical microscopy image of PFO alone. The concentrations of PFO and SWCNT are 1.0 g/L and 0.33 g/L, respectively. For experiment of (d), SWCNT was not contained. A glass plate is used as the solid surface.
