UNIDIRECTIONAL ORIENTATION OF NEMATIC LIQUID CRYSTALLINE POLYMER-GRAFTED SEMICONDUCTOR NANORODS ON A RUBBED POLYIMIDE ALIGNMENT LAYER |
| 초록 |
Inorganic semiconductor nanorods are considered promising materials to fabricate optical and electrical nanoscale devices. Integration of individual nanorods on a solid substrate in an ordered manner is indispensable to draw effectively their fascinating intrinsic properties. Here nematic liquid crystalline (LC) polymer-grafted nanorods were demonstrated to form unidirectionally aligned structures by a conventional LC alignment technique. Polymerization initiator moieties were immobilized onto the surfaces of ZnO nanorods (average diameter 7 nm; length 50 nm) at controlled densities. Nematic LC methacrylate polymers were grown by atom transfer radical polymerization from the modified nanorods. At a moderate grafting density, the unidirectional orientation of nanorods was attained by spin-coating onto a rubbed polyimide layer together with small nematic LC molecules by surface-assisted hierarchical molecular ordering via cooperative molecular interactions among LC mesogens. |
