Development of New Inorganic-Organic Hybrids by Sol-Gel Process, and its Dielectric Properties |
| 초록 |
Development of new organic-inorganic hybrids with high value of dielectric constant has received much current interest for various electronic applications, such as embedded capacitors, multi-layer ceramic capacitors (MLCC), printed circuit boards (PCB), etc. But, it is very difficult to incorporate pre-crystalline ceramic powders (BaTiO3 in particular, which is known to exhibit very high value of dielectric constant) into the organic matrix due to very low dispersibility of the crystalline particles. Therefore, the synthesis of crystalline BaTiO3, highly dispersible in organic medium and then development of new organic-inorganic hybrids there from with high value of dielectric constant is the main focus of this work, which was not explored yet. Crystalline BaTiO3 (70-100 nm) for this work, was synthesized at ~70oC by the reaction between Ba(OH)2.H2O and H2N(CH2)2NH2 modified Ti(OPri)4 precursor. Organic-inorganic hybrids with different compositions were prepared by incorporating different proportion of crystalline powder (1-10 wt%) into the partially hydrolyzed 3-methacryloxy propyl trimethoxy silane (MPTS) system and the precursors were deposited on glass substrates by spinning technique (2000 rpm, 20 s). Hybrid films were characterized by XRD, FTIR and SEM and the study of dielectric properties showed that hybrid films exhibited relatively high value of dielectric constants depending on their compositions. |
