A composite system of Fe3O4 nanoparticle-doped chiral nematic liquid crystals (N*LC) with flexible display performance was proposed. Fe3O4 nanoparticle and the nanoparticle-doped N*LC composite were detailed prepared and investigated. The influence of nanoparticle doping amount and chiral compound content on the magnetic performance as well as electrical performance of the flexible device had been studied in detail. The most suitable N*LC composites for magnetic-driven display had been found. With the characteristics of simple preparation, good stability and high resolution, the Fe3O4 nanoparticle-doped N*LCs had promising applications for power-free magnetic-driven flexible LC paper or display board. @@@ [GRAPHICS] @@@ .
