TY - JOUR TI - Smectic liquid-crystalline order in suspensions of highly polydisperse goethite nanorods AU - Vroege, G.J. AU - Thies-Weesie, D.M.E. AU - Petukhov, A.V. AU - Lemaire, B.J. AU - Davidson, P. T2 - Advanced Materials AB - Optical Bragg reflections and small-angle X-ray scattering (see figure) reveal that dispersions of Goethite (FeOOH) nanorods spontaneously form layered (smectic A) structures, although their 55% length polydispersity exceeds the theoretical limit by a factor of three. Here, sedimentation and size partitioning contribute to a very rich phase behavior including nematic and columnar phases. This suggests the application of the self-organizing tendencies of such mineral liquid crystals to obtain materials with very diverse nanostructures.
