High Dielectric BaTiO3-polyimide Nanocomposites by the Sol-Gel Route |
| 초록 |
The use of BaTiO3 as a dielectric in multilayer ceramic capacitors (MLCCs) and embedded capacitors in printed circuit boards are very well known. In most of these applications BaTiO3 is generally dispersed in an organic polymer matrix for improved processability. Polyimides are a class of organic polymers known for their high thermal and chemical stabilities as well as high mechanical strength and they find extensive use in electronic and packaging industry. The use of BaTiO3-polyimide hybrids as a high capacitance material for MLCCs and embedded capacitors is not well studied. We have synthesized a new class of inorganic-organic hybrid materials by homogeneous dispersion of BaTiO3 in a polyimide-silicone organic polymer using sol-gel method. Thin films of the hybrids were obtained by single spin coating on ITO-coated glass surface. The films were characterized by infrared spectra, X-ray, SEM and TEM. The variation of dielectric constant of the hybrid films with change in filler concentration was studied. |
