Compositional and Property Optimization of UV-Cured Thick Film Dielectrics on Flexible Films |
| 초록 |
UV-cureable high k BaTiO3-based materials on flexible substrates have been investigated in terms of physical and dielectric properties of resultant thick films. Dielectric pastes prepared by mixing the BaTiO3 powders and a commercial UV curing polymer using a three-roll mill were printed on flexible ITO films and then cured by exposure to a UV light at a moderate temperature of ＜ 40oC up to 60 min in air atmosphere. Dielectric properties of the thick films were measured at room temperature for the samples containing BaTiO3 from 20 to 70 wt. % over the broad frequency range of 103 to 107 Hz. Dielectric constant tended to increase with the increase of BaTiO3 content and to decrease with the increase of frequency. For the optimized composition with BaTiO3 content, promising dielectric constant of ＞30 and tan δ ＜ 0.1 were obtained. This study proposes the possibility of fabricating flexible high k thick film capacitors by the simple UV curing process at near room temperature. |
