摘要

Polymer cholesteric liquid-crystal flakes suspended in a fluid with nonnegligible conductivity can exhibit motion in the presence of an ac electric field. The plateletlike particles with a Grandjean texture initially lie parallel to the cell substrates and exhibit a strong selective reflection that is diminished or extinguished as the flakes move. Flake motion was seen within a specific frequency bandwidth in an electric field as low as 5 mV_(rms)/μm. Flakes reoriented about their longest axis to align parallel to the applied field, and a rise time of 560 ms was seen in a 40-mV_(rms)/μm field at 100 Hz.
