SANS intensities of deuterated SWNTs mixed with contrast-matched L121/water (red color) compared with SAXS intensities (blue color) for (a) the lamellar phase and (b) the reverse hexagonal phase. The mixing ratio of SWNT/L121/water was (3.9/61/39). The flat SANS intensity of contrast-matching that of L121/water at each phase (black color) is shown as a reference.
