Abstract
Carbon nanotubes (CNTs) can exist as clusters whenever doping amount in nematic liquid crystal (LC) mixture exceeds critical point. Based on experimental observation of electric field-dependent shape of the CNT cluster, it elongates along the field direction and its original morphology of the cluster is restored after the removal of the field. The elongation was fully reversible only below a certain breakdown field. Both clusters and elongated CNTs were observed under nonpolarized and polarized light. The cluster absorbs incident light completely while the elongated one absorbs light propagating along the long axis only. Utilizing the field-controlled cluster, light modulation for display application is possible.
