Liquid crystal nanoscience & soft self-assembly

The emerging field of liquid crystal nanoscience crosses the borders between classic liquid crystal research and nanotechnology. Examples are the liquid-crystalline phase behavior of nanoparticle dispersions, the self-assembly and alignment of nanomaterials in liquid-crystalline media, and the synthesis of nanomaterials by using liquid crystals as ‘templates’ or ‘precursors’ [H. K. Bisoyi, S. Kumar, Chem. Soc. Rev. 40, 306 (2011)].

During the last years our group together with Siegmar Roth’s group at the Max Planck Institute of Solid State Research pioneered the simultaneous dispersion and alignment of single-wall carbon nanotubes in water-based lyotropic liquid crystals. In close collaboration with Rudolf Zentel (Mainz) and Jan P. F. Lagerwall (now Seoul National University) we recently contributed to studies on the microfluidic synthesis of liquid crystal elastomer particles.
