Liquid Crystals: Reversible Fragmentation and Self-Assembling of Nematic Liquid Crystal Droplets on Functionalized Pyroelectric Substrates (Adv. Funct. Mater. 15/2012)



original image

Pico-femtoliter nematic liquid crystal droplets are fragmented on a functionalized lithium niobate substrate covered with polydimethylsiloxane (PDMS) circular microstructures. On page 3267, Francesco Merola and co-workers report that the droplets move and assemble themselves outside or inside the structures, driven by electric field lines that are generated by the pyroelectric effect.
